Why do we keep debating the obvious? Don't we all know that a good diet and physical exercise are beneficial? Does anyone dispute that?
That would seem to be a given. The only difference of opinion would seem to lie in the amound of emphasis placed on those things. I said earlier that none of us is going to get out of here alive, and that would seem to be beyond debate. The only argument would seem to be how much factors like diet and exercise improve a particular individual's overall well-being, and how many hours, days, months, or years might be added to a given individual's life.
I like to keep "active," but my personal definition of "active" would probably be looked down on by the guy who spends an hour in the gym every day and eats vegan. These are individual lifestyle decisions, not doctrine, and I say, to each his own.
I suspect there are some, maybe quite a few, who read these fitness threads and wish they could do more along those lines, but who simply can't for physical reasons beyond their control. And I also suspect that many of these guys may have spent their lives "stacking the odds in their favor" until an unexpected health event robbed them of their vigor and their vitality.
