Scientist Quotes

Physical immortality is seductive. The ancient Hindus sought it; the Greek physician Galen from the 2nd Century A.D. and the Arabic philosopher/physician Avicenna from the 11th Century A.D. believed in it.
Reducing caloric intake is the only proven method of extending life. If caloric intake is reduced to 20 percent below maintenance, you can extend your lifespan considerably.
Researchers have been looking for biomarkers of age for a long time and have failed. People sell tests out there to measure your biological age, and none of them work. There's no evidence that you can measure biological age with any reliability.
Someone will eventually succeed in this hunt for a longevity pill, and when they do, one of the greatest advances in the history of medicine will have been achieved.
The bodies we have are not made for extended use. We must cope with accumulated DNA damage, cell damage, muscle atrophy, bone loss, decreased muscle mass, and joints worn out from overuse during a lifetime of bipedal locomotion. It might have worked great for prehistoric humans, but it wreaks havoc on our knees and hips.
The evolutionary theory of senescence can be stated as follows: while bodies are not designed to fail, neither are they designed for extended operation.
The fact is that nothing in gerontology even comes close to fulfilling the promise of dramatically extended lifespan, in spite of bold claims to the contrary that by now should sound familiar.
The Faustian trade of the 20th century was, we got 30 years of additional life, but in return we got heart disease, cancer, stroke, Alzheimer's and sensory impairments. The question is: What Faustian trade are we making now, as we go after heart disease, cancer, stroke and Alzheimer's?
The field of ageing research is full of characters. We have hucksters claiming that cures for ageing can be bought and sold; prophetic seers, their hands extended for money, warning that immortality is nigh; and would-be Nobelists working methodically in laboratories in search of a pill to slow ageing.
The last thing you ever want to do is extend the period of frailty and disability and make people unhealthy for a longer time period. So lifespan extension in and of itself should not be the goal of medicine, nor should it be the goal of public health, nor should it be the goal of aging science.
The modern rise of Alzheimer's Disease in the twentieth century is not a sign of failure. It's a sign of success. Success in living long enough to see that disease expressed.
The only control we have over the duration of our life is to shorten it, and we do that all the time.
The real problem is that there's a tendency to associate ageing with loss and decline and things that aren't desirable. But experiencing all that there is to experience in life - whether that's at the age of ten or thirty or fifty or eighty - is what life is all about.
The reason we have cancer and heart disease is the same reason you can't get rid of the wear and tear on your tires on your car: as soon as you use them, you are wearing them away. You can't make eternal tires, and it's the same with the human body.
The vast majority of studies say anti-aging supplements don't work.
The way that we are going after ageing, I think, is a problem. The modern medical model is basically designed to attack one disease at a time. Independent of all other diseases and independent of the basic process of ageing itself.
There is a possibility that there is somebody out there alive today over 122, but we'll probably never know it, because in all likelihood they come from either China or India, and they don't have reliable birth records.
There is no empirical evidence to suggest that ageing in humans has been modified by any means, nor is there evidence that it is even possible to measure biological age. And nothing has been demonstrated to be true when it comes to anti-ageing medicines.
We have grown accustomed to the wonders of clean water, indoor plumbing, laser surgery, genetic engineering, artificial joints, replacement body parts, and the much longer lives that accompany them. Yet we should remember that the vast majority of humans ever born died before the age of 10 from an infectious disease.
We know in the field of aging that some people tend to senesce, or grow older, more rapidly than others, and some more slowly.
