believe food plastic
In Hollywood they're getting younger, but believe me, it's not the food. It's the plastic surgery.
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.
adopting advances behavioral educated habits harmful life medical members missing population sure technology
I'm not sure the least educated members of the population are missing out on the advances in medical technology as much as they are adopting harmful behavioral habits that shorten their life.
ageing bought claiming cures extended field full money pill prophetic slow warning
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 biological evidence looking measure none people sell tests time work
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.
age looks mean outdoors people seems skin spend time
Just because someone looks old doesn't mean he or she is. The skin of some people who spend a lot of time outdoors seems to age very rapidly. Someone can look 80 or 90 and only be 40 to 50.
extension nor science
Lifespan extension has never really been a goal of aging science, nor should it.
eventually extended life
I have little doubt that gerontologists will eventually find a way to avoid, or more likely, delay, the unpleasantries of extended life.
computing copying ears increases internal organs power stories xerox
Growing new limbs, copying internal organs like a Xerox machine, exponential increases in computing power, better eyes and ears - I could read stories like this endlessly.
