If we do everything right, the best we can do is live out our potential with as little age-related disease and disability as possible.

In Genesis 6:3, it says man can live to be 120, but there is no scientific basis for it.

If you can slow the biological process of aging, even a minor slowdown in the rate at which we age yields improvements in virtually every condition of frailty and disability and mortality that we see at later ages.

Ageing is very rare. We only see it in humans and laboratory animals and in zoo animals and in our pets. Basically, organisms that are protected from the external world. Once you create that protection, you live long enough to see ageing.

People pushing the idea that everyone can live to be 100 are perpetuating a myth that goes all the way back to the Bible.

The only control we have over the duration of our life is to shorten it, and we do that all the time.
