I once looked at conditional lifespan data given that one reached a particular age. What was interesting that for India and Mongolia, countries with very different cultures, lifestyle, diet and climate, after 75 years the remaining lifespan was the same.
Granted in both countries those who died after 75 lived presumably most of their life a traditional lifestyle with little influence of modern factors like junk food, TV at night, work stress etc. So we cannot conclude that those factors have no influence after 75th birthday. Still people should be rather skeptical about attributing to a particular factor really long life.
To a point. There are diminishing returns where genetics begins to play more of a factor.
For many people no amount of exercise is going to help them when they're 90 because they'll die before they turn 90. Jim Fixx[0] is the perfect example of this
Unless we develop a cure for Parkinson's disease I doubt Michael J. Fox[1] will live to 90, no matter how much exercise he does, because of the effects that disease has had on his body and the side effects from the treatments that he has received.
Another way to look at it is to substitute 90 with 100, 110, or 120. Or to think about what kind of exercise and healthy eating tips that you would recommend to a person with Down's Syndrome to help them live to be 90.
People who can should absolutely exercise and eat healthy food but that is no guarantee that they will live full healthy lives.
