She sees her physician at a Malaysian government clinic regularly. My wife takes care of her well-being like any daughter would do. She is the oldest among her siblings, who grew during the Japanese occupation in the Second World War. She also saw how the British rubber planters lived in her small town of Rantau, Negeri Sembilan, Malaysia. In the 1960\u2019s she saw at every evening British rubber planters and their wives congregated at a club house in the centre of the town till the early hours. We hope she can live till 100 years. We read an interesting article by Damian Whitworth in the Times London on September 30th on advances made in the area of ageing. He reported research works done by geneticist David Sinclair, who is a longevity expert who believes we will soon be able to boost our genes to defy the ageing process He interviewed David Sinclair who is a professor at the Harvard Medical School, Cambridge, USA. He is a 50-year old and believes that the pioneering work he and other human biologists are doing could help him to live for another 80 years. He is an author of a book, Lifespan: Why We Age-and Why We Don\u2019t Have. The following is an extract of the interview. David Sinclair, an expert on ageing, has some extremely eye-catching things to say about how long we might live and what that means for the future of our species. Hewould like to see the 22nd century. \u201cThat would mean making it to my 132nd year. To me, that is a remote chance, but not beyond the laws of biology or way off our current trajectory,\u201d he writes inLifespan, his new book about how medical science is changing our futures. Jeanne Calment, who is believed to have lived longer than any other recorded person, died in France at the age of 122 in 1997. By the turn of the next century a 122-year-old will be thought of as having led a full life, but not a particularly long one, Sinclair says. Hitting 150 may not be out of reach. And then? \u201cThere is no biological law that says we must age.\u201d We are, he says, about to \u201credefine what it means to be human, for this is not just the start of a revolution; it is the start of an evolution\u201d. Sinclair runs a laboratory at Harvard Medical School, where he is a professor in the department of genetics and a co-director of the Center for the Biological Mechanisms of Aging. He runs a sister laboratory at the University of New South Wales in Sydney, Australia, where he grew up. He made his name in the mid-2000s when he demonstrated that the natural chemical resveratrol mimicked calorie-restriction in yeast and made the cells live longer. In 2013 he made headlines with his work to stimulate longevity genes in mice so that the effects of ageing were reversed and old mice found new vitality. I had been expecting, after reading his book with its bold claims, to encounter a grand figure, but Sinclair is relaxed and understated in conversation. Clearly, though, he is not shy of making the sorts of assertions of which many scientists are usually wary. \u201cWell, the world, in my view, is sleeping on the job,\u201d he says. \u201cI\u2019ve just spent the last two years seeing results in my laboratory and in my colleagues\u2019 laboratories that I thought I\u2019d never see; finding that there\u2019s a back-up hard drive of youthfulness. In 50 years\u2019 time it\u2019s really impossible to imagine the kinds of advances that\u2019ll be possible.\u201d Sinclair works on sirtuins, which have been dubbed \u201clongevity genes\u201d. There are seven sirtuins in mammals, made by almost every cell in the body. They control health, fitness and survival, and require a molecule called nicotinamide adenine dinucleotide (NAD). The diminishment of NAD as we age is understood to be a primary reason why our bodies develop diseases when we are older. Longevity genes can be activated by exercise, intermittent fasting, low-protein diets and exposure to cold temperatures, Sinclair says. \u201cBut over time, diet and exercise are not sufficient. We need more than that.\u201d That\u2019s where science comes in. NAD increases the activity of all seven sirtuins. Sinclair\u2019s research has found that old mice that were fed nicotinamide mononucleotide (NMN), an NAD-boosting molecule, suddenly started running ultra-marathons. NAD boosters extend the lives of mice. There are indications that NAD boosters may restore the fertility of old mice, and positive signs from another trial in mares. The implications are enormous if women can look forward to extending their fertility window. Sinclair is careful to say that what happens in mice might not necessarily happen in humans, but \u201cif that works in women the way it\u2019s working in mice and in horses, then women can start to think differently about their lives\u201d. Sinclair predicts that another key path to prolonging youth will be cellular reprogramming, in which ageing cells are reset \u2014 like DVDs that have had their scratches removed and lost information restored. Shinya Yamanaka won the Nobel prize in physiology or medicine in 2012 for discovering that a set of genes could turn adult cells into pluripotent stem cells, which can become any other cell type. Sinclair\u2019s team is working on developing this \u201cswitch\u201d to reset cells in the petri dish and then, he hopes, in the body. He envisages a day when we could be administered a specially engineered virus carrying reprogramming genes that are switched on by an antibiotic. A person in their forties would feel 35 again. Then 30 and 25. \u201cTheoretically you could reset tissue or the entire body every ten years,\u201d he says. \u201cWe don\u2019t know how many times we can reset, but that\u2019s one of the exciting areas of the field.\u201d The very significant downside could be that the process causes cancers. \u201cBut I\u2019ve been pleasantly surprised that we reprogrammed mice with a virus last year and those mice are still fine \u2014 no evidence of any downsides.\u201d A third part of the approach that Sinclair outlines in his \u201cinformation theory of ageing\u201d is attacking senescent, or \u201czombie\u201d, cells. These are cells that have stopped dividing, but aren\u2019t dead. They can cause inflammation, and while restoring them would be a tall order, a class of drugs \u2014 senolytics \u2014 are being developed to kill them, which should aid rejuvenation, according to Sinclair. He is not a medical doctor, so he won\u2019t give advice, but he does share details of how his knowledge of the frontline research on ageing shapes his daily life. His aim is to walk a lot of steps each day, take the stairs, and lift weights and run at the weekend at the gym, where he also takes a sauna and dunks in an icy pool. He tries to stay cool during the day and when sleeping. His diet is plant-heavy, but he\u2019ll eat meat after he has done a workout. He tries to miss one meal a day or have one very small one. His sugar, bread and pasta intake is low, and he gave up desserts a decade ago. Every few months he has his blood analysed for biomarkers and makes adjustments to his diet and exercise if anything shows up. He doesn\u2019t smoke and avoids microwaved plastic, excessive exposure to UV, x-rays and CAT scans. As well as daily doses of vitamin D, vitamin K and aspirin, he takes a \u201ctriple combo\u201d of anti-ageing supplements. NMN is made by our cells and found in avocados, broccoli and cabbage. It increases the levels of NAD in the body, but you\u2019d need to eat an awful lot of avocado toast to achieve the same effect as the gram that Sinclair takes at breakfast. Metformin, a derivative of French lilac, is used as a diabetes medication, but shows signs of prolonging vitality. In studies it has been seen to increase the lifespan of mice, and among human users it apparently reduced the likelihood of dementia, cardiovascular disease, cancer, frailty and depression. Sinclair takes a gram of that too, along with a gram of resveratrol in his homemade yoghurt. Resveratrol, which is found in red wine, protects against many diseases and extended the lifespan of yeast cells and fruit flies. Is this good news for boozers? Not really. The dose Sinclair takes \u201cwould be the equivalent of about 500 glasses of wine for breakfast\u201d. He drinks the occasional glass of red wine. Sinclair was a co-founder of a company that was set up to test resveratrol, which he promoted as \u201cclose to miraculous\u201d. The company was sold to GlaxoSmithKline, which allegedly ended the research because the results were underwhelming. Sinclair, who made a reported $8 million from the sale, says that he would love to \u201creinvigorate\u201d the programme. His sprightly 80-year-old father is on the same regimen as Sinclair, who has even put the three family dogs on NMN. He shows me the ring he wears that monitors his heart rate, body temperature and movements. This is just the beginning of the way in which we will monitor ourselves as companies read our genomes and monitor our glucose, the oxygen levels in our blood, vitamin balance and hormones, and diagnose neurodegenerative diseases from subtle changes in our movement long before symptoms are noticeable. Is there not a danger that all this data will result in losing some of the fun of life? \u201cYou can combine fun and fact,\u201d Sinclair says. \u201cIt\u2019s not for everybody. A third of the population, at a rough guess, is really interested in their long-term health and would love to have some additional incentives.\u201d He has done some \u201cconservative\u201d maths about what scientific developments will achieve over the next 50 years. DNA monitoring will soon be alerting us to diseases long before they become serious, allowing us to start treating cancer and other conditions earlier \u2014 that could give us an extra ten years of life. Eating fewer calories and fewer animals, doing more exercise and getting cold enough to boost the development of \u201chealthy\u201d brown fat, which research suggests correlates with longevity in rodents, could add another five years. Molecular treatment to turbo-charge our longevity genes could add another eight. Then we could reset our epigenome \u2014 the control systems and cellular structures that govern which genes should be turned on and off \u2014 with molecules or genetic modification, destroy senescent cells with drugs or vaccinations and replace worn-out organs with those from genetically altered farm animals or 3D printers. All this might add another decade. That\u2019s 33 years added to the roughly 81-year life expectancy of a person in the UK. And we won\u2019t be decrepit old people; we will be full of vitality. Yet will a life expectancy of 114 be just for the rich? Sinclair warns that we stand on the brink of a world in which the wealthy could ensure that their children, or even their pets, live far longer than the children of those living in poverty. \u201cSome of these medicines might be very expensive initially, though they\u2019ll come down in price.\u201d And don\u2019t those rejuvenated people eventually become incapacitated? \u201cThey will,\u201d he says, but the research suggests they\u2019ll die quicker. The expensive people are the ones who are sick for a long time. Sinclair is unusually energetic, and you can imagine him carrying that into deep old age. But what if millions and millions of the rest of us are quite happy to be ancient and fit, but just want to sit around? \u201cWe can\u2019t retire at 65 and live another 65 years,\u201d he says. \u201cIt\u2019s just not tenable. It\u2019s not fair to the younger people. There will have to be adjustments.\u201d We\u2019d have to address our levels of consumption to make living on our planet sustainable and to avoid the environmental crisis becoming further exacerbated by a growing, ageing population. Our social security systems can\u2019t support half a life of retirement. \u201cWe are flying blind into one of the most economically destabilising events in the history of the world,\u201d Sinclair says. He doesn\u2019t have all the solutions. Critics suggest that there is a temptation for those in the highly lucrative field of longevity research to over-hype what is possible, although Sinclair tells me that \u201cincome to my family from my inventions is put back into medical research and innovation\u201d. Jeffrey Flier, a former dean of Harvard Medical School, this year criticised the publicity on longevity studies. \u201cIf you say you\u2019re a terrific scientist and you have a treatment for ageing, it gets a lot of attention,\u201d he said on the website Kaiser Health News. \u201cThere is financial incentive and inducement to overpromise before all the research is in.\u201d What Sinclair says he wants more than anything is for everyone to expect to meet their great-great-grandchildren. By knowing future generations, he argues, we will feel more accountable for our actions today. \u201cIt will compel us to confront the challenges that we currently push down the road,\u201d he says. \u201cTo invest in research that won\u2019t just benefit us now, but people 100 years from now. To worry about the planet\u2019s ecosystems and climate 200 years from now.\u201d Note: Lifespan: Why We Age \u2014 and Why We Don\u2019t Have Toby David Sinclair is published by Harper Thorsons.\", \"UK English Female\");\n                }\n            };\n        <\/script>\n    \n\n\n\n<p>My mother in-law is 85 years old and watches her diet carefully.

But what if millions and millions\nof the rest of us are quite happy to be ancient and fit, but just want to sit\naround? \u201cWe can\u2019t retire at 65 and live another 65 years,\u201d he says. \u201cIt\u2019s just\nnot tenable. It\u2019s not fair to the younger people. There will have to be\nadjustments.\u201d<\/p>\n\n\n\n<p>We\u2019d have to address our levels of consumption to\nmake living on our planet sustainable and to avoid the environmental crisis\nbecoming further exacerbated by a growing, ageing population. Our social\nsecurity systems can\u2019t support half a life of retirement. \u201cWe are flying blind\ninto one of the most economically destabilising events in the history of the\nworld,\u201d Sinclair says. He doesn\u2019t have all the solutions.<\/p>\n\n\n\n<p>Critics suggest that there is a temptation for\nthose in the highly lucrative field of longevity research to over-hype what is\npossible, although Sinclair tells me that \u201cincome to my family from my\ninventions is put back into medical research and innovation\u201d.<\/p>\n\n\n\n<p>Jeffrey Flier, a former dean of Harvard Medical\nSchool, this year criticised the publicity on longevity studies. \u201cIf you say\nyou\u2019re a terrific scientist and you have a treatment for ageing, it gets a lot\nof attention,\u201d he said on the website Kaiser Health News. \u201cThere is financial\nincentive and inducement to overpromise before all the research is in.\u201d<\/p>\n\n\n\n<p>What Sinclair says he wants more than anything is\nfor everyone to expect to meet their great-great-grandchildren. By knowing\nfuture generations, he argues, we will feel more accountable for our actions\ntoday. \u201cIt will compel us to confront the challenges that we currently push\ndown the road,\u201d he says. \u201cTo invest in research that won\u2019t just benefit us now,\nbut people 100 years from now. To worry about the planet\u2019s ecosystems and\nclimate 200 years from now.\u201d<\/p>\n\n\n\n<p><strong>Note:&nbsp; <\/strong><\/p>\n\n\n\n<p><strong><em>Lifespan: Why We Age \u2014 and Why We Don\u2019t Have To<\/em><\/strong><strong>&nbsp;by David Sinclair is published by Harper\nThorsons.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>My mother in-law is 85 years old and watches her diet carefully.
