Exercise >>> Mortality ... Was Re: Exercise >>> Immunity

[Guest guest]

Whether exercise will afford bennies to CR practitioners will depend

upon the degree of CR and their success at choosing the proper ON

particulars, will it not? If you know precisely the amount of CR

necessary to preserve physical function into advanced aging in absence

of exercise, please tell me now.

Also, most of those studies stated they corrected for CVD factors. The

y examined huge cohorts many of whom were Asymptomatic. This should

minimize tainting of data and results. Besides what's the downside of

doing a little bit to much exercise? Too much fitness? Too much strength?

We don't know.

Each does their own thing.

Within the confines of what I read, I prefer to err on the side of moderation, but that's just me.

I have an 85yo friend in Wilmington, NC, runs a bookstore downtown.

He runs every morning, I think 5 miles, and he's done that for at least 15 yrs.

But some health event caused him to start.

Another friend, ran for at least 20 yrs, every morning 5 miles, before work. He retired at 65yo and died after retirement. I'm pressed by the people who die, more than the live ones, they conduct tests on.

I'm especially impressed because women can outlive men (recently) by a significant factor not exercising at all and overweight. Something built into them a survival factor because of mortality perhaps, that now causes them to live longer, after lowering the mortality from childbirth, bleeding, etc. Maybe it's because they do more work.

Regards.
