This is Longevity Support.
S.G.D. Weinall asks, correlation between looking young and longevity.
We know that when we show images of people to research participants or just raters on the internet, how old they guess a person is does correlate with other signs of their health and longevity.
There was a famous study a number of years ago by the Danish demographer Cor Christensen that compared the faces of older female twins The raiders of these faces were reliably able to pick the identical twin who was going to live longer based on which face looked older.
Expedito asks, is it possible to halt aging and will it be in our lifetimes?
Depends on who you ask.
Some people believe fervently that they can stop or even reverse the aging process and that this innovation or this breakthrough is just around the corner.
