The bonds of friendship are universal and elemental. In Friendship, journalist Lydia Denworth visits the front lines of the science of friendship in search of its biological, psychological, and evolutionary foundations. Finding it to be as old as life on the African savannas, she also discovers that friendship is reflected in our brain waves, detectable in our genomes, and capable of strengthening our cardiovascular and immune systems. Its opposite, loneliness, can kill. As a result, social connection is finally being recognized as critical to our physical and emotional well-being. With warmth and compassion, Denworth weaves together past and present, field biology and cutting-edge neuroscience, to show how our bodies and minds are designed to make friends, the process by which social bonds develop, and how a drive for friendship underpins human (and nonhuman) society. With its refreshingly optimistic vision of the evolution of human nature, this book puts friendship at the center of our lives.

    I not only read this, I wrote it! So I am understandably biased. But upon re-reading it in preparation for publication, I've realized something important. People ask about books you read that change your life. I can say that reporting this book changed my life. It gave me permission to hang out with my friends more. I hope it will do the same for everyone else who reads it. I not only read this, I wrote it! So I am understandably biased.

It is well-written and easy to read. What I've found in the book: 1. There is an evolution basis for friendship. Friendship (social bond between non-kins) does not only exist in human society. The author described several animal studies, especially primates. A study of the structure of social relationships among female baboons in Moremi, Botswana shows: 1) the strength of females’ social bonds is the most important factor in their reproductive success. 2) females who have strong and stable social bonds live longer. 2. Friendship can mean different things to different people. Number of friends may not matter much for some, but the quality does matter for all. Ambivalent relationship is not ambivalent--it is just bad. One research says: "Men are more likely to build relationships that focus on what friends can do for them, what opportunities they can open, what kind of resources they can provide—all of which Hall describes as agency. Women, on the other hand, are more likely to expect their closest friends to offer emotional nourishment and support." Does it still stand, especially in younger generation? It sounds too stereotypical to me. 3. Chapter Four is the friendship in child development. A lot of common sense is validated by science. For example: 1) Puberty a turning point for dealing with stress, and it comes with the bad news for parents: "Up to the age of ten, mothers calmed down the amygdala by engaging prefrontal circuitry in children’s brains that works to control stress. In adolescents, who were eleven to seventeen in this study, Mom’s presence no longer worked the same magic. The brain’s response to stress remained highly reactive. On the plus side for teenagers, the necessary brain circuitry for managing the stress—a network that connects the amygdala to the prefrontal cortex—is more fully developed, so they are on their way to mature responses." 2) It is not peer-pressure, but "peer effect." “The presence of peers is so powerful during adolescence that it can make even mice misbehave,” Steinberg wrote in his 2014 book Age of Opportunity, "Pressure doesn’t have to come into it, merely presence...We came to the notion that basically when kids are around other kids it primes their reward system to be more easily aroused and more easily activated. That in turn leads them to pay undue attention to the potential rewards of a risky choice and relatively less to the potential costs.” As my mother has told me (and her mother had told her), parents should worry about whom their kids are hanging around. Your kids' health requires them to have friends, which also means peer influence is inevitable. 4. Online friendship Apparently various studies of social media's influence on people's mental health have produced mixed results. One researcher says: “Using social media is essentially a tradeoff,” Hancock says. “You get very small but significant advantages for your well-being that come with very small but statistically significant costs.” What’s more, the overall effect on well-being, meaning the amount of variation among individuals that could be attributed to technology use when all effects were combined, was “essentially zero,” Hancock says. To be specific, it was 0.01 on a scale in which 0.2 is considered a small effect size. A more nuanced questioning is needed: "The overwhelming attention to time on social media (both frequency and duration of use) ignores content or context. The very concept of screen time is essentially meaningless given the variety of possible ways to occupy that time. Who and what we interact with matter as much or more than for how long." However, the author does not mention the highly addictive nature of these social media tools, which is a feature not a bug. In my view, this feature can only lead to worse, not better, outcome in the users' mental health and relationships. 5. The role of friendship in physical and mental health and the deficit of such can cause serious physical and mental damage. “Human beings,” they would go on to write, “have a pervasive drive to form and maintain at least a minimum quantity of lasting, positive, and significant relationships.” The consensus, Silk wrote, was that human friendships were “intimate, supportive, egalitarian relationships.” They required compatibility and an investment of time. When asked, “What have you learned?”, George Vaillant, the longtime director of the Study of Adult Development at the Harvard University Health Service, replied: “That the only thing that really matters in life are your relationships to other people.”

    I got an early copy of the book and I already feel like it has had an impact on me. It is a great kick off book for 2020. Instead of skipping wine in January for my health, I'm having more wine and seeing friends which is far more important and fun. It is a great read filled with both great science and personal anecdotes on the importance of investing in our most basic relationships. It makes a compelling argument for doubling down on good friends. I thoroughly enjoyed it. I got an early copy of the book and I already feel like it has had an impact on me.

    This is a collection of other studies about mirroring and the need to bond. Basically, our brains are geared toward social interactions. This is basic evolutionary biology covered in a lot of other books. It is useful to have a focus on just one thread (friendship), but it did not seem all that new.

    It was a chore to get through this book. It’s more about primates than anything, and reads like a literary review in many instances. The author spends more time introducing a researcher’s background than the research itself.

    I loved a lot about this. I had a lot of friends as a teenager, but I often felt bad for wanting to be with them. I have tried not to pass that on to my kids and realize how important friends are to teenagers and this book is filled with the science to back up my feelings. As an adult I have found some really amazing friends and the ones that want to give back to the relationship with me are the ones I still hang out with and see. Friendship goes two ways.

Making time for friends and making time for our kids to have friends is important to happiness and bonding with other humans. If you think you don’t need friends, science says otherwise. Go hang out with your friends and make it a regular thing! (Sometimes the science behind all the claims was boring to me. But maybe that was because I didn’t need much convincing.)

It is remarkable to find out how friendship has influenced and been influenced by human evolution, and the actual biological power of the friendship bond.

They are all so memorably drawn that what could be an overwhelming amount of information is easily absorbed and remembered. Finding out that friendships have an important role to play in the biological advantages affecting evolution was totally intriguing. I highly recommend. A perfect gift for friends on Valentine's Day!

    Though I appreciate the wide sampling of sources collated into a single volume, "Friendship" doesn't reach for revelatory depth. The strongest theme in the book is the author's personal anecdotes about her family, which while not unrelated or forced, end up becoming central to the book, the main take-away.

Global context aside, this was an excellent read. Denworth handles this complicated, primal, and deeply personal topic with great care and strikes just the right balance between being playful and informative. Her ability to cull information from fascinating and groundbreaking studies in neuroscience and primatology to support her central thesis--that friendship is much deeper and much more important than many, if not most, of us recognize--is impressive and makes for a compelling read. I can't wait to hug my friends again.

    Lydia Denworth’s Friendship translates cutting-edge science in telling a compelling story that details and underscores how close connections are not only necessary - they will extend, and potentially save, our lives. She reveals and revels in a topic that is universally important and endlessly interesting.

    I love this book as it talks about the science of friendship. Mix in a bit of monkey science with attachment, friendship in school, the deepness of connections, heredity or genetic expression, and rounding it off with the impact on our lives... woo! Much of this science is current and up-to-date. It's been a while since I've read something that triggered about 20 more books into my "to-read" list. Highly recommended for anyone who wants to think about what makes friends tick. Friendship must be I love this book as it talks about the science of friendship.

    Lydia Denworth's comprehensive look at the evolution and necessity of friendship is highly informative and engaging. I don't think I've ever devoured a nonfiction book quite this quickly, and that was all due to Denworth's writing style--she ably breaks down even complicated scientific terms and ideas so anyone can understand them by illustrating unfamiliar concepts with stories and analogies from her own life.

Learning more about what scientists are currently discovering about the importance of friendship would have been compelling enough (spoiler alert: friendship is highly important to our health and well-being at all points of our lives) but she also takes us through the all the primate studies that have been conducted through the past several decades. Interestingly, primate research teaches us that friendship is much older than humans are, suggesting that it is not just a nice thing to have; it's a biological imperative. Denworth wraps up with an exhortation for us to pay attention to and cultivate our relationships even if we feel we're too busy for friends because just like neglecting our health, the ramifications of neglecting our friends could lead to loneliness in later life, and that loneliness has been proven to be just as deadly as any of our current health crises. Everyone should read this book and then go hug their friends and family members.

It is a very wonky exploration of the effects of friendship, loneliness, and lack of connection on our overall health and by extension life fulfillment and longevity.

(a relatively new area of study) In between the many many case studies and journal articles, there are some very interesting facts and information on attachment, social connection, and bonds as we age. I was most intrigued by facts on adolescents and the importance of peer approval, social media's role in maintaining quality relationships, and the types of friendships. The downside of this book is that it is filled with scientific studies mainly dealing with primatology and neuroscience that can be a little monotonous. I wish the book was broken up into more anecdotes and easily digestible facts and information. Overall, it is a good read if you want to get into the weeds of the importance of friendship and connection in combatting the long term effects of loneliness.

It is beautifully written and seamlessly weaves cutting edge science with the essential role of friendship. I was completely engaged by the clear explanations of the work of the scientists who have studied multiple species—from rhesus monkeys to zebra fish—to explain our interactions with certain people and what we expect and, more importantly, what we receive from those with whom we bond. I am certainly not the only one who understands how important and timely this book is. It was just selected by the Next Big Idea Club (Malcolm Gladwell, Susan Cain, Adam Grant, and Daniel Pink) as one of the six must-read nonfiction Books of Winter 2020! For years now I have been inundated with the all the reasons why meditation improves my health. I am not knocking meditation, but as Ms. Denworth so eloquently illustrates, through clear and fascinating explanations of the neuroscience as well as personal observation, friendship is the foundation of a healthy life, well lived. After reading this book, I hugged all my friends (perhaps they were a bit bemused) and then I wanted to make new friends. My reasons were perhaps self-interested but like the monkeys and fish I knew it was essential to my well-being. I am a committed but poor meditator but, because of this book, I now know what it means to be a good friend and to have good friends. You would be well served to understand that too.

That was the take-away from a client meeting I had a year or so ago. Like many people, the client was older, single and lived alone. Contrary to the client's normal ways, a Saturday evening dinner was canceled because the client was under the weather. The next morning the client called in sick to teach Sunday School, and upon hearing this news the client's astute and caring friend new something was amiss and showed up at the client's door. Visibly disoriented, the client's friend knew medical attention was needed. Refusing the astute friend to call 911, the client agreed to be driven to the ER. And then the client's memory fades to black. Afterwards the ER doctor told the client "had you stayed at home one hour longer, you would be dead." Septic shock nearly killed my client. A friendship saved a life. Today I finished reading Friendship: The Evolution, Biology, and Extraordinary Power of Life's Fundamental Bond by Lydia Denworth. Her book pulled this memory from the back of my mind to the forefront. As an estate planning and probate attorney I spend my days preparing client documents related to illness and death. And I see the strain on faces when I ask who will be your health care agent? Who will be your backup? So many people have no obvious answer, and the stress is visible. Denworth's book is heavy on the hard science behind friendship, however, it is worth pushing through if you are more of a social policy student like myself. Sprinkled throughout the book are the personal stories that bring the science to life, at least for me. From birth to retirement age (and beyond), Denworth discuss how friendships are formed, and the benefits they provide. My take-away from this book is that a power of attorney for health care is important, forming the bonds to know who to name is critical. The more "isolated" an individual feels, the greater the risk of illness. Denworth states "those who answered that they had five or fewer interactions per month with close friends and family were considered isolated". Meaning mortality risk was increased. My only criticism of the book is that it was a bit lite on the how of friendship. She touches on the role of co-workers, faith-based organizations, community groups, and a group of friends and family. I would have enjoyed a bit more discussion, and suggestion, on how to build the critical face-to-face time into our busy lives. I can say her book influenced me. While reading this week my youngest asked for a sleepover on Friday night with 2 friends. My first thought was "no, we have a busy weekend, yada yada yada." Thinking about Denworth's discussion of her children's friends I went against my instinct and not only said "sure", but also invited a fiend of my son's to stay over as well. So our house will be filled with 5 children's voices Friday night. And when they have trouble settling down and not talking, I'll remind myself that they are forging critical friendship bonds, a lifelong need.

    Poignant time during quarantine to have read this book about how social isolation is as big of a risk factor for mortality as smoking. Super interesting read overall though. How crazy is it that we think it’s crazy to realize that spending our time cultivating a deep and meaningful social network of friends is ACTUALLY medically/societally/personally valuable towards physical health and longevity? It seems obvious and yet..

    Great book with lots of research. Denworth communicated tough scientific and psychological theories, experiments, and concepts in easily relatable and graspable language. She covers the evolutionary and biological need for friendships and how and why our brains respond to friendships the way they do. I wish there had been more about the evolutionary biology of friendships and less about the impact of social media.

    This is a great book on why you should have friends. I also appreciated the distinction it draws between types of personalities and friendships: solitude is when you're ok with not having / having few friends; loneliness is when you want more friends than you have. Loneliness has a detrimental effect that is comparable to trauma (e.g. poverty). It is a book that's sympathetic to the lack of friends and the physical impact it has on people (people with close knit communities live longer).

The author also works to make this book relate-able - there's lots of anecdotes about her and her children's personal friends, though I did notice that the friendships describe seem to be same-gender friendships.

'The clearest message we get from this 75-year study is this: Good relationships keep us happier and healthier. Period." A good reminder at any time, but particularly this, as we find ourselves simultaneously isolated from friends and distant family and the outside world and in closer proximity than ever to our nuclear family or cluster.

My only disappointment, if it can even be called as such, is that apart from prosetylizing the need for friendship, it does little to point those in need in a direction that could help them gain more friendships. It would be a nice addition for sure.

    This was an interesting read about the evolutionary purpose of friendship and biological underpinnings. I was delighted to learn that even fish have some fish version of pals. Sort of poignant to read about our need for social connection when we're all housebound, especially the older folks who might be in particular danger from loneliness. If you're looking for a book that will make you want to call up and reinforce your ties to others, I would recommend The Village Effect.

    Interesting book. Some of it is kinda obvious, but the studies showing the physiological effect friendship can have (not just mental) is really cool. By the same token, loneliness can be very detrimental to your health. Especially with the pandemic, it's so important to keep up your friendships. Interesting book.

In 1975, in E.O. Wilson’s Sociobiology: The New Synthesis, presented the idea that genes make us do what we do socially, namely it was not just culture that impacted our social behavior, was very controversial. However, scientific proof is now on Wilson’s side. The book starts near this point, and raises the question of why is friendship so important to our lives? What are the evolutionary forces that give friendship an advantage? The book moves back and forth (in a progression of chapters) between the evolutionary forces, the comparative analysis with other species, the current understanding of the biology of our bodies and those of other primates, and the implication of friendship (and bonds between individuals) at various ages: infants, teenagers, and older adults. It also takes us right up to ongoing studies, often collaborations between neuroscientists and sociologist, in understanding the brain patterns of friends (for example why some people’s friendship clicks, and others do not, and even trying to predict friendship between people). Let me give some examples. In primates and in humans, the bonding of mother and child is critical to the development of brain patterns and the behavior of the child. Lack of those interactions has significant implications for the development of the child’s social skills. Knowing this it is unconscionable of separating children and babies from mothers. This will have a lasting negative impact. And with teenagers, the emotional part of the brain develops much faster than the reasonable part. What is really interesting is that those individuals with strong networks of friends (and support) tend to weather illnesses better (and there are biological proofs of this through existence of certain levels of specific chemicals); in loneliness, those chemicals are missing and thus lonely people tends to have higher levels of “inflammation”, which leads to greater affinity to disease. And there is a strong case the people should continue to be engaged in meaningful networks of people as they age, since it is “keeps them younger.” While much (not all) of these facts are known, what the author does is put them in a larger context of friendship (one definition is that friendships are intimate, supportive, egalitarian relations (p 133)), in the relatedness of behavior with other animals, and taking us right to the edge of experiments today. While there were a few sections that I did not have the same high opinion of, I thought the book one worth reading to understand the value of friendship at all ages of life, and WHY this is so important to our bodies and our lives. The book concludes with a statement about the oldest of our population, and cites work done at Harvard over a 75 year period (an amazing study). I provide a link to the TED talk of “What makes a good life”. Robert Waldinger: What makes a good life ... - TED Talks https://www.ted.com/talks/robert_wald... I hope you will pick up a copy of this book and read it. Quoting Robert Waldinger “The only thing that really matters in life are your relations to other people.” “Good relationships keep us happier and healthier” (mentally and physically). The book helps explain why!

    This book primarily gives an overview of studies among primates and humans concerning the bases and results of friendship. It concludes that friendship is a cross-species phenomena based on both nature (genetic) and nurture (environment). It also gives lots of support to friendship being essential to our remaining in good health. One interesting chapter is that discussing the effects of social media on friendship.

It concludes that friendship is a cross-species phenomena based on both nature (genetic) and nurture (environment). It also gives lots of support to friendship being essential to our remaining in good health. One interesting chapter is that discussing the effects of social media on friendship. The conclusions drawn are that social media is not the cause of loneliness and disaffection, but that it exacerbates it. Also, close friends on social media tend to have face-to-face contact as well, not just on social media. Friendships also increase our likelihood to reproduce. The book is richly footnoted, so the reader can do follow up study on topics of interest. Some interesting thoughts from the book: The term "emotion contagion" is used and is explained as something happening with the other person is also happening to you. Support is divided into 3 types: "emotional support" which makes us feel cared for, "instrumental support" is more tangible-providing some tangible help (child care, food, etc.), and "informational support" is sharing information. Diversity of friendship types provides health protection. Degree of control and participation in our health care provide for better results. "Studies show that these happy relationships provide a sense of purpose and meaning, they improve our outlook, and they encourage us to engage in better health behaviors." "...play accomplishes a lot. It allow young animals to learn without stress. It invites exploration. It fine-tunes self control, both physically and emotionally. It serves as practice for things that will be done later in life." A 2017 study showed that there are one million new neural connections per second in early childhood, but that brain circuits are a use-it-or-lose-it proposition. The frontal cortex regulates judgment, planning and executive function and is still developing during the teen years. Also during the teen years, the limbic system (responsible for emotion) mature more quickly. "The limbic system...undergoes a spurt of development earlier. Its line more closely resembles a shallow bell curve, rising above the prefrontal cortex line and then dropping again and flattening out to rejoin it." Adolescents are more likely to behave recklessly when with their friends. A researcher, Joan Silk, found human friendships are intimate, supportive and egalitarian. Other researchers found that the bond should be strong, stable, and equitable and that servicing of shared social needs leaves both parties better off. "Friendship makes you feel good. It includes a willingness to help, especially in times of need." People who are more open to new experiences were more likely to have friends who live far away, were older or younger and whom they didn't see regularly, but still felt close. "Sometimes we feel so close to other people that we mistakenly remember things that happened to them as having happened to us."

    From macaques monkeys to teenagers, gaboons to senior citizens, Lydia Denworth carefully and methodically presents research and history of the study and data around friendships. Three main lessons emerged in this outstanding book : 1/ Social connections are really good for us, and loneliness kills. 2/ Quality matters as much or more than quantity. 3/ People In a Harvard study by Robert Waldinger found that those most satisfied at age 50, more then cholesterol or blood pressure or any other data p From macaques monkeys to teenagers, gaboons to senior citizens, Lydia Denworth carefully and methodically presents research and history of the study and data around friendships. Three main lessons emerged in this outstanding book : 1/ Social connections are really good for us, and loneliness kills. 2/ Quality matters as much or more than quantity. 3/ People In a Harvard study by Robert Waldinger found that those most satisfied at age 50, more then cholesterol or blood pressure or any other data point, were the healthiest at age 80. Also reported, by Steve Coles loneliness study at UCLA in his work on gene expression and the immune system, found that while loneliness increased and other forms of adversity increased susceptibility to inflammation and viral infection, social integration and feeling fulfilled seemed to have the opposite effect improving the immune systems ability to fight off those ills. While friendships are empirically proven to extend and improve health outcomes, ambivalent relationships, relationships of convenience are found to be damaging to health. Teens were found to make poorer choices when around friends. In fact, they were 4 times more likely to make poor choices. Imagine that. A fascinating fact presented, that I have also read with respect to neurological study of fear, that while we may be drawn to those who process the world in much the same way we do, our minds might actually be changed literally by our association with these people. In short, be around someone super anxious and projecting lack of confidence in our relationships, our romantic partners, or our jobs, and our brain may follow and sync to these same brain waves as those we keep around us. FMRI studies and hyper-scanning at Harvard and Dartmouth are beginning to show that brain waves can become synchronized with those we associate. Choose wisely. A delightful program was reported where senior citizens in Los Angeles participate in elementary schools as volunteer aids in classrooms. The result of the program , everyone feels loved. Seniors blood pressure improves, they lose weight, they become more functional, their life is extended when their loneliness decreased. Denworth compared a survey where spouses and partners in the United States considered their romantic partner to be their best friend, while in Mexico for example the best friend was not the romantic partner. Different cultures. These just some of the examples presented by Lydia Denworth in support of the vital evidence of friendships make for more healthy and longer lives. And outstanding book and a quick read.

    I picked up Lydia Denworth's book "Friendship" because I know there is something very powerful about friends, and was curious to get her perspective on it. I know my own friends add to my life immeasurably, and wanted to understand more about why that is. Denworth's book is about the nature and power of the bond of friendship and its role in evolutionary sociobiology. She starts the book discussing the notion of whether individuals of other species can be said to have friends, or whether friends I picked up Lydia Denworth's book "Friendship" because I know there is something very powerful about friends, and was curious to get her perspective on it.

Denworth's book is about the nature and power of the bond of friendship and its role in evolutionary sociobiology. She starts the book discussing the notion of whether individuals of other species can be said to have friends, or whether friendship is a uniquely human phenomenon. Does friendship have deep evolutionary roots, or is it a relatively new concept? It turns out that friendship is deeply rooted in the tree of life, but much research still needs to be done to determine why. One interesting discovery is that friends have an outsize impact on our biological health. In the book, Denworth explores friendship in some of our nearest evolutionary relatives, then discusses friendship and its influence on each life stage, from newborns to senior citizens. I was really struck by how important and necessary friends are to overall health. Indeed, one's friendship network is a rough barometer for how long someone will live. Truly interesting. One thing that she did not touch on much is how friendship networks differ between extroverts and introverts, but perhaps that will be in a follow-on book. Overall, Denworth writes well and keeps the reader's interest with many stories. I would recommend.

    I thought I'd be enthralled with this book as friendship is one of the topics that interests me most. And I thought it'd be a quick read since I'm reading it during the pandemic but no on both accounts. I found it grueling and had to force myself to finish it. I'm not sure exactly what was wrong with it. I felt as if Denworth included a lot of information on many studies in different areas, but not with enough depth for me to be truly interested. This was especially true in the earlier chapters I thought I'd be enthralled with this book as friendship is one of the topics that interests me most.

This was especially true in the earlier chapters on ethnobiology and neurology. Either topic is interesting on its own, but reading lists of experimenters with a few details on what they did didn't make a huge impression on me. The later chapters which focused more on the sociology and psychology of friendship were more interesting and easier for me to read yet I can't say I came away having learned anything much really new about friendship. Looking through the notes, though, I know there are some studies and a TED talk or two I will want to follow up on to learn more about specific studies in more detail.
