aging attention days dogs duration enhancing focus humans life mice span sure work
What we know for sure from our work and from others' is that mice have a life span of 1,000 days, dogs have 5,000 days, and we humans have 29,000 days. Recognizing that the duration is limited, and aging is inevitable, focus the attention on enhancing the quality of the days you have.
designed extended neither stated theory
The evolutionary theory of senescence can be stated as follows: while bodies are not designed to fail, neither are they designed for extended operation.
additional century life question return sensory stroke trade
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?
added age cancer cannot chronic cures decades diseases effect increase lead life miraculous smallpox vast
While eliminating smallpox and curtailing cholera added decades of life to vast populations, cures for the chronic diseases of old age cannot have the same effect on life expectancy. A cure for cancer would be miraculous and welcome, but it would lead to only a three-year increase in life expectancy at birth.

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.
claims close contrary extended fulfilling promise spite
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.
alive birth china either likelihood reliable somebody today
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.
age ageing biological empirical evidence humans modified nor possible suggest
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.
extend life period trying
We're not trying to make us live forever; we're not trying to even make us live significantly longer. What we're trying to do is extend the period of healthy life.
duration life time
The only control we have over the duration of our life is to shorten it, and we do that all the time.
