Six simple things that increase life expectancy

Fox News as a useful summary available here. I had one issue to raise:

In fact, studies suggest that daily exercise can add up to three years to your life. . . .

Assuming one works out one hour a day, that you are awake for 16 hours a day, and a zero interest rate, in 48 years you would have spent an amount of time exercising to the increase in life expectancy. Discounting by even a small interest rate would dramatically reduce the number of years that one would have to exercise before the work canceled out the benefit.

Of course, if you do a form of exercise you enjoy, then it's a win-win rather than a cost/benefit analysis.
