I would not be surprised to find out that each of us are born with a genetic age limit, which no amount of good food or exercise will ever be able to increase.

It's undeniable though that exercise improves the quality of life. Whether it increases the quantity beyond maybe an extra 3-5 years on average, who knows? But to a dying man, ask what he'd pay to live one more day, much less 3-5 years. Probably everything he had, so I think it's worth the effort to try to get those extra years, even though they may not seem like a lot right now.
