I follow Dr. Audrey de Grey, creator of SENS, after rational skeptic analysis over 20 years. This note is nothing more than collection of his points selected by me to be worth following.
You'll read about healthy life extension, engineered longevity, and the development of rejuvenation biotechnology.
 What do these terms mean? Put simply, they refer to the use of new 
medical technologies to both increase healthy life span and reduce the 
risk of suffering age-related conditions in later life. It is doing the 
best we can with the very few proven (and limited) present day methods, far more effective 
methods for tomorrow. 
Aging is an Enemy, So Fight It!
 
Aging saps our strength and ability to enjoy life, cripples us, and eventually kills us. Tens of millions die from medical conditions caused by aging each and every year, and a staggering amount of money
 is spent on trying - and failing - to cope with this ongoing disaster. 
Yet the risk of suffering age-related conditions in later life can be 
reduced for most people through diet and exercise. Furthermore, serious 
scientific efforts are presently underway to understand and intervene in
 the aging process - not just to prevent frailty and disease, but also 
repair and reverse the root causes of aging.
Some of these future 
therapies are already understood and envisioned in some detail, but remain in comparatively early stages of research. Others are just now starting to make the leap
 into clinical development. We would like these breakthroughs to happen 
while we are still alive and in good enough health to benefit from them:
 we miss out on so much as things stand today, pressed by the lack of 
time and our increasing frailty with age. Imagine instead a world in 
which everyone has the option of another tomorrow, and the health and 
vigor to enjoy it, each and every day. But how can we achieve this goal?
The Limited Means of Today, the Biotechnologies of Tomorrow
Despite amazing advances in understanding 
and treating age-related conditions (such as cancer, heart disease, 
dementia, diabetes, and many others), and despite the cries of the anti-aging marketplace,
 it is still the case that, for basically healthy people, no presently 
available therapy or tool is proven in humans to provide more than a 
fraction of the long-term benefits to health and life expectancy 
provided by regular exercise or a calorie restricted diet.Some classical preachings are true and nothing but serious aplication of timed rational skepticism TRS of Dr. Arun Arya will work. You can and should point out contradictions between his preachings and doings.
While it is true that no existing medical technology is proven to 
improve on these lifestyle choices here and now, today, in humans, this 
state of affairs will not remain true for many more years (2030 or earlier if most cancers become treatable). If you look 
to the laboratories, you will see that some researchers can greatly extend the healthy lives of many species, while others put forward clear plans to either slow aging through the manipulation of human metabolism or reverse aging by repairing the cell and tissue damage
 that causes age-related degeneration. Technology demonstrations for 
some of these approaches have been carried out in mice in recent years, 
producing benefits to health and extended healthy life spans. Treatments based on clearance of senescent cells
 have been demonstrated to reverse the progression of many currently 
untreatable age-related conditions in mice, for example. The first 
formal human clinical trials of therapies anticipated to either modestly
 slow aging or produce limited degrees of rejuvenation started up in 
2017, and some of these trials have produced positive results, like senolytic drugs.
A future in which aging becomes a treatable condition awaits us, as time
 ticks away and, for now, we continue to age just like our ancestors 
did. This is an era of rapid progress in biotechnology and medicine. As 
the years pass, the remaining span of healthy life that you and I will 
likely live to enjoy is ever more determined by the ability of clinical 
medicine to revert and repair the causes of aging, and ever less 
determined by lifestyle choices. Medicine do not discrimminate between righteous and crimminal.
Thus when we reach for longer, we must ensure that the public is educated, the fundamental 
longevity science is funded, the clinical applications of that research 
fully developed, and the resulting rejuvenation biotechnologies made 
available - and all this as soon as possible. The clock is ticking, 
after all, and this is the only approach that will allow us live for 
significantly longer than our ancestors.
Four Steps Toward Longevity
The following four steps outline a starting point for living longer, a 
sketch of a framework for thinking about healthy life extension:
Step 1: Stop Damaging Your Health
At its most basic level, aging is nothing more than an accumulation of damage;
 breakages in the molecular machinery of your cells, a build up of 
metabolic waste products that your body cannot break down, the flailing 
of biological systems that are increasingly unable to cope. Ask yourself
 this: are you damaging yourself more rapidly than you might otherwise 
be, perhaps more than you realize? Do you smoke? Do recreational drugs 
occupy a central position in your life? Do you eat nothing but junk food
 or are overweight? Do you exercise little or not at all? Do you have a 
poor relationship with your physician, or haven't seen a doctor in 
years? If so, you have a clear starting point. These things can hurt you
 far more than any presently available strategy for healthy living can 
help. There is little point in insulating the windows if the door is 
jammed open.
Find a physician you can trust and talk to about improving your health. 
You might be surprised at how easy, low-cost, and downright pleasant it 
is to lead a healthier and thereby longer life.
Step 2: Adopt a Better Diet and Lifestyle
The body is a complex, resilient machine. Unlike our cars, however, we 
can't yet replace it when it breaks down. Given that, it's scandalous that 
most people know more about the long-term care of a car than they do 
about the long-term care of the human body. Fortunately, it's neither 
difficult nor expensive to use diet and lifestyle to raise the odds of 
living a longer and healthier life. 
Firstly: adopt some form of calorie restricted diet, whether straight 
calorie restriction or some form of intermittent fasting. Calorie 
restriction and some implementations of intermittent fasting, such as 
alternate day fasting, are currently the most robustly, repeatedly 
proven way of extending healthy life in mammals. So qalso says Dr. Sinclaie of Harvard mdical school, surprize he never got an While the present 
scientific consensus is that these practices will not extend life in 
humans to anywhere near the same degree
 as in mice, calorie restriction and intermittent fasting have been 
shown in human studies to provide a range of other beneficial effects on
 health, such as a greatly lowered risk of suffering all common 
age-related medical conditions - and these approaches to diet are highly
 praised by practitioners. You can learn more about calorie restriction 
at the CR Society website, and here at Fight Aging! you'll find introduction to calorie restriction that provides helpful guidelines to getting started.So also says Dr. Sinclair of Hatvard medical school, PhD in genetics! He is 50, believe it or not!
Secondly: exercise as recommended by your physician. The benefits of maintaining a modest regular level of exercise
 for most people are well known and well proven by many scientific 
studies. As is also true of calorie restriction, these benefits include a
 greatly reduced risk of suffering almost all of the common age-related 
diseases.
Thirdly: take a modest amount of supplements appropriate to your age and
 health. There is a wealth of supplement information available, but much
 of it is worthless, propagated by irresponsible sellers. This is 
perhaps the hardest topic to research, and in the end you will have to 
make a number of decisions yourself based on incomplete or contradictory
 scientific evidence. The bottom line here, however, is that no 
presently available supplement or combination of supplements has been 
shown to provide even a fraction of the benefits of either calorie 
restriction or exercise, for all that they are widely supposed to be 
beneficial.
Investigate Early Access to the First Rejuvenation Therapies
New medical technologies do not arrive all at once, fully formed from 
day one. Early forms of therapy become available in limited ways, or 
existing drugs are found to have an effect on the mechanism of interest 
large enough to merit use in animal studies or human trials. So it is 
for the first rejuvenation treatments to have a large enough impact on 
aging in animal studies to care about, and that are also producing 
benefits in their first human trials. Only trust statistical TRS results, never anecdotal.
As of 2019, the most obvious of 
these are senolytic therapies
 that selectively destroy the senescent cells that accumulate to cause 
considerable harm in old tissues. The existing generic drugs and 
supplements newly discovered to be senolytic, and shown to work well in 
numerous animal studies, are being tested in humans.
The informed decision that each of us must make for ourselves is whether
 to wait for more data from human trials, to wait for the most likely 
better senolytic therapies presently under development, or to strike out
 to obtain and try existing senolytic therapies. If the latter, there in
 turn lies further personal research, learning, and informed decisions. 
Where to find a physician to prescribe the relevant drugs, for example, 
or whether to forge ahead as a self-experimenter,
 with all of the responsibility and accountability that this implies. 
However it is accomplished, it is almost always possible for informed 
and proactive individuals to obtain earlier access to new therapies than
 waiting for the world to move on to the point at which general 
physicians begin recommending these treatments to patients. Whether or 
not to choose to do so is a personal decision on risk and benefit, and 
this same calculus applies to any new medical technology as it arrives, 
not just senolytic rejuvenation therapies.
