Summary
A startling chronicle that takes us onto the frontiers of the science of aging， and reveals how close we are to an astonishing extension of our lifespans and a vastly improved quality of life in our later years。
Aging--not cancer， not heart disease--is the world's leading cause of death and suffering。 We accept as inevitable that as we advance in years our bodies and minds begin to deteriorate and we are more and more likely to be felled by dementia or disease。 But we never really question--is it necessary？ Biologists， on the other hand， have been investigating for years， wondering if the decline of our bodies is truly unavoidable。 After all， there are already tortoises and salamanders whose risk of dying is the same as long as they live。 With the help of science， could humans find a way to become old without getting elderly， a phenomenon otherwise known as "biological immortality"？
In Ageless， biologist Andrew Steele shows us that the answer lies at the cellular level。 He takes us on a journey through the laboratories where scientists are studying every aspect of the cell--DNA， mitochondria， stem cells， our immune systems， even age-genes that can lead to a ten-fold increase in life span （in worms， anyway）--all in an effort to forestall or reverse the body's （currently！） inevitable decline。 With bell-clear writing and intellectual passion， Steele shines a spotlight on a revolution already underway and offers reality-based hope。

The book is a bit too scientific for my test。Too complicated， too difficult to follow

Heavy， heavy on the science， @ 90% of the book。 Light （about 10%） on actionable tips to stave off the ill effects of aging。 Skip the biochemistry unless you're into that sort of thing and proceed to the last sections of the book。 Heavy， heavy on the science， @ 90% of the book。 Light （about 10%） on actionable tips to stave off the ill effects of aging。 Skip the biochemistry unless you're into that sort of thing and proceed to the last sections of the book。 。。。more

An exciting book to read if you are scientifically- inclined。 I learned a lot about why we age， and the potential for what scientists may be able to accomplish to cure age-related illnesses。 No good solutions as yet though。 The authors takes a deep dive into stem cell research and what it can do to help us fight illnesses as we age。 A great book to read！

Do you want to live a long time？ How about forever？In Ageless， Steele presents the science of aging and its history because， through understanding， the whys and hows to live longer are clearer and more compelling。 With each year that passes， the average age of death gets pushed back by roughly three months due to improved medicines， therapies， and nutrition。 If new medicines and therapies can be developed quickly enough， then it might be possible for one year to be added for each year we live， o Do you want to live a long time？ How about forever？In Ageless， Steele presents the science of aging and its history because， through understanding， the whys and hows to live longer are clearer and more compelling。 With each year that passes， the average age of death gets pushed back by roughly three months due to improved medicines， therapies， and nutrition。 If new medicines and therapies can be developed quickly enough， then it might be possible for one year to be added for each year we live， or five years， or ten years。 And this might give us or our children or our children’s children the chance to live much healthier， more active， and longer lives。 It might even mean an entire halt to aging。And Steel does just that; he presents the history of the field， as well as the most recent studies currently being conducted。 This requires the majority of the book， leaving a mere 50 pages to present what action can be taken now。 But this is a plus， reading less like some guru’s ten-point program and more like a weighty， yet accessible， overview。Throughout the book， he suggests that aging is a disease， not an inevitable outcome。 Each 7-8 years of life essentially doubles the chance of death， so that an 80-year old is sixty times more likely to die than a 30-year old。 If science is able to slow aging， then the risk of cancer， heart disease， dementia， and other diseases associated with old age will be significantly reduced for all of humankind。 。。。more

Pretty informative in a decent style。 Obviously very biology focussed。 Learnt some things that I will probably adapt to my lifestyle although most are pretty common sense

Too speculative This book is speculative to the point of near uselessness in practical terms。 It’s interesting if you want to know about the earliest studies happening related to anti-aging， but there isn’t much that is actionable for today aside from the common sense advice of not smoking， eating a healthy balanced diet and exercising。

Although I gave this book a five-star rating， I have somewhat mixed feelings about it。 First， the writing is excellent， at least in the chapters I understood。 The problem for me was that the first two parts of the book were pretty technical。 I have a degree in physics but you almost need a degree in chemistry and biology to follow some of the narrative。 I'm getting older and I tend to like books that are easy to read。 But， the final two chapters made the book worth the price。 In the next to last Although I gave this book a five-star rating， I have somewhat mixed feelings about it。 First， the writing is excellent， at least in the chapters I understood。 The problem for me was that the first two parts of the book were pretty technical。 I have a degree in physics but you almost need a degree in chemistry and biology to follow some of the narrative。 I'm getting older and I tend to like books that are easy to read。 But， the final two chapters made the book worth the price。 In the next to last chapter he lists eleven things we can do to live longer。 Most of these we know （exercise， eat right， get enough sleep， etc。） But for me the real reward was in the final chapter where he writes about metformin， a drug that is used to treat diabetes。 Research has shown that the drug may also reduce the risk of cancer and dementia and extend lifespan by a bit。 I'm going to call my doctor tomorrow to see if she'll prescribe it！ 。。。more

This is really more of a 3 1/2 star situation for me。 I enjoyed the book， but it was a little dry on the science side from time to time。 This isn't a bad thing， it's just not exactly what I was expecting。 The advice for what to do now is pretty obvious， but Steele goes into an in-depth explanation as to why， which I liked。 There are really interesting and exciting horizons in this field。。。 and after reading this book I'm a bit more aware of what getting old is all about。 This is really more of a 3 1/2 star situation for me。 I enjoyed the book， but it was a little dry on the science side from time to time。 This isn't a bad thing， it's just not exactly what I was expecting。 The advice for what to do now is pretty obvious， but Steele goes into an in-depth explanation as to why， which I liked。 There are really interesting and exciting horizons in this field。。。 and after reading this book I'm a bit more aware of what getting old is all about。 。。。more

I'm uncertain how to rate this book。 On the one hand， it's well written and brings us up to date （in considerable detail！） on the science of aging: what's happening in our bodies as we age， what could be done about it， and what is the current state of research on these methods （in 2020）。 It also points out usefully that to delay aging （extending youth） would be very valuable in terms of health， because much ill health is age-related， so extending youth much improves general health。On the other h I'm uncertain how to rate this book。 On the one hand， it's well written and brings us up to date （in considerable detail！） on the science of aging: what's happening in our bodies as we age， what could be done about it， and what is the current state of research on these methods （in 2020）。 It also points out usefully that to delay aging （extending youth） would be very valuable in terms of health， because much ill health is age-related， so extending youth much improves general health。On the other hand， it doesn't tell you anything that will be of much use in extending your own youth。 Chapter 10 has practical recommendations， yes， but they're recommendations that most people will already be familiar with， if they have any interest in the subject: don't smoke， don't eat too much， exercise， get enough sleep， get vaccinated， wash your hands， clean your teeth thoroughly （apparently this affects general health！）， avoid sunburn。The high level of technical detail in some chapters of the book gives it credibility， but it's overkill for me and probably for many other general readers who aren't scientists。 I resorted to skimming to get through this stuff; it would be indigestible if I tried to read every word of it。In the end， I value the book because I simply didn't know that science had advanced this far， so that practical techniques for youth extension should become available in the short to medium term: within this century， I suppose。Also， I was fascinated to read that some techniques could not just slow the process of aging， but reverse it: restoring youth。 This would enable anyone to benefit who was not actually dead at the time of treatment。 。。。more

It’s technically a good book which is very detailed on the scientific studies that are currently underway on the extension of human lifespan。 All aspects seem to be covered from cell replication， stem cell research， glycation of proteins to dietary restriction。 However， if you’re looking for answers to what you can do now to extend your life， then it’s limited。 It appears that we’re at an early stage of research and it’s a complicated subject。 It seems that our bodies are on a knife-edge of posi It’s technically a good book which is very detailed on the scientific studies that are currently underway on the extension of human lifespan。 All aspects seem to be covered from cell replication， stem cell research， glycation of proteins to dietary restriction。 However， if you’re looking for answers to what you can do now to extend your life， then it’s limited。 It appears that we’re at an early stage of research and it’s a complicated subject。 It seems that our bodies are on a knife-edge of positive and negative molecular reactions - using stem cells can extend life but can increase the risk of cancer if used in the wrong environment。 Every positive has a negative。Steele wants the book to be a call to action for everyone， including governments， to start focusing on treating ageing， instead of treating the individual results of ageing - cancers， heart disease， diabetes， dementia， Parkinsons， etc， that come from old age。Spoiler alert - in the penultimate chapter， Steele has these as summary headings:1。 Don’t smoke。2。 Don’t eat too much。3。 Get some exercise。4。 Get 7-8 hours sleep a night。5。 Get vaccinated and wash your hands。6。 Take care of your teeth。7。 Wear sunscreen。8。 Monitor your heart rate and blood pressure。9。 Don’t bother with vitamins。10。 Don’t bother with longevity drugs yet。11。 Be a woman。One thing that I did pick up on， （which was only a single sentence） was regarding glycation of proteins - sugar is bad for the body and causes glycation （inflammation/rearrangement of cells）， leading to impaired elasticity of tissues such as blood vessels， skin， and tendons。 He mentions that fructose seems to be more of a problem than other sugars…I eat a lot of fruit so I’m going to cut down on that。 Also he didn't discuss hydration - it's one of my rules for being healthy， to stay hydrated， but maybe it doesn't affect lifespan。。。。or he's just not looked at it。Overall though， despite it being a tour de force on the subject， I’m left feeling disappointed because there doesn’t appear to be anything new that we can do to increase our lifespan - we’ve got to wait for science to catch up。 。。。more

I have mixed feelings on this one。 The author seems very excited about telomeres， and senescent cells and epigenetics。 Okay， fair enough， but he has a very biased viewpoint about anti-ageing research that really troubled me。 It troubles me that this scientist has such tunnel vision about the potential of these treatments， particularly in the hands of rich and powerful people。 While individual human lifespans are lengthening， there is this other little thing called climate change。 As it is， we ar I have mixed feelings on this one。 The author seems very excited about telomeres， and senescent cells and epigenetics。 Okay， fair enough， but he has a very biased viewpoint about anti-ageing research that really troubled me。 It troubles me that this scientist has such tunnel vision about the potential of these treatments， particularly in the hands of rich and powerful people。 While individual human lifespans are lengthening， there is this other little thing called climate change。 As it is， we are facing widespread disease and destruction due to loss of habitat， the spread of disease， natural disasters and their fallout。。。 so many challenges that we know are directly caused by having too many people on this planet。 I was really frustrated by the lack of balance in the book。There was some pretty interesting research， but maybe there’s a part of me that actually hopes that we never find a “cure” for ageing。 I wonder if we should let nature take its course。 Science has brought many breakthroughs for humans and we are getting better and better at surviving， but we do it through dominating the land and destroying it。 。。。more

This is a fascinating book for fellow science geeks， but it's not a book on how the reader is necessarily going to avoid aging。 Steele is a scientist who takes us on a deep dive into the 9 reasons he says we age。 He maintains that aging is not required and that if we can manipulate cells enough， it may be possible for people to never age in the future。 That's the thing though， this is all futuristic stuff。 It's all cell manipulation and promising technology。 It is quite interesting， but I'm not This is a fascinating book for fellow science geeks， but it's not a book on how the reader is necessarily going to avoid aging。 Steele is a scientist who takes us on a deep dive into the 9 reasons he says we age。 He maintains that aging is not required and that if we can manipulate cells enough， it may be possible for people to never age in the future。 That's the thing though， this is all futuristic stuff。 It's all cell manipulation and promising technology。 It is quite interesting， but I'm not even sure that I agree with him that our governments should be funding this research， as I really think it would end up being one more area where the rich benefited and life got even harder for the poor。 The very end of the book tells how to live a little longer in the meantime in order to hopefully extend your life enough to live in times when they can extend it more and then more。 These are absolutely basic things we all know -- stop smoking， exercise， get sleep， etc。 He says not to take supplements （even vitamins）。 The last one is "be born a woman。" I was surprised that Steele didn't go into other things we do know help extend life， like social contact。 He also talked a lot about the length of telomeres and how that translates to life expectancy， but never mentions things like the fact that they've shown that growing up in an abusive home and other sources of stress actually shorten telomeres。 Then there's the giddy fascination he has with all the scientists who sew mice together to study how that affects them （for instance， sewing a young mouse to an older one to see if the old one benefits from sharing cells and such）。 He actually uses the word "shockingly" when he says this research mostly stopped 30 years ago， but then he happily tells us that a married couple of scientists have started doing it again。 Then he tells us about the experiments they're doing on King Charles spaniels in order to try to develop anti-aging technology to sell to dog owners （apparently this breed ages quickly）。 He sees this all as wonderful science。 I just felt sad。 It is an interesting book for those who just love learning。 I found it very interesting， but not actually helpful on a personal level。I read a digital ARC of this book via Net Galley。 。。。more

Steele makes some interesting points especially about the longevity of different species， some getting a far better run than others。 We humans do okay but whales and tortoises， wow！ He claims that aging is not a natural thing， its a disease and should be treated as such。 It's a short book and mostly he tries to make the case that the government should be funding more research into aging。 Fair enough， but it tends to detract from the info he is trying to convey to the reader。 Steele makes some interesting points especially about the longevity of different species， some getting a far better run than others。 We humans do okay but whales and tortoises， wow！ He claims that aging is not a natural thing， its a disease and should be treated as such。 It's a short book and mostly he tries to make the case that the government should be funding more research into aging。 Fair enough， but it tends to detract from the info he is trying to convey to the reader。 。。。more
