Steve, of course present longevity is risible compared to other longevities, my point is that if we can increase our healthspan, which is our healthy lifespan, we might have a probability by following certain guidelines.
Longevity in the sense of living up to 120 years has not much meaning, since after 100 there is usually not much strenght in the body nor in the mind. Definitely there is not after 110. Let's say that, presently, reaching a centenary age does not seem to bring about particular advantages.
Whereas, lowering the probability of degenerative disease until a certain age, may seem desirable.
