There's better evidence for that than for practically any
other intervention. Maybe more evidence for it than all
other interventions combined!


I think this conclusion will be reversed when researchers
realize that sarcopenia and osteopenia are much greater
threats to longevity in people over, say, 60 years of age than
bodymass per se. IOW, extrapolating animal models to humans
is not reasonable here.

It is most likely to affect longevity. The effects on QOL
vary.

Jesus! That list of horrors sure supports my case!

Not only do they live longer but they a physically more active in their

playing tennis when they are 120 years old.


You certainly have an active imagination. There is no objective
evidence that caloric restriction in humans would have the same effect
as in mice.


I thought there was some evidence that periodic fasting was
advantageous, prompting the body to go into a repair cycle. But maybe
that was just speculation regarding studies on mouses.

Yeah, but how much is enough....it varies...



You know . . . . enough. People can generally tell when they're getting
enough sleep, right? Can't they? I can . . . I just assumed that it was,
um, obvious?

Roger, you can try calorie restriction which has proven to extend
lives of some animals by about 50%. Scientific American did an article
about this.

http://www.sciam.com/article.cfm?art...mber=1&catID=2

Excerpt:

Our hunt for cr mimetics grew out of our desire to better understand
caloric restriction's many effects on the body. Scientists first
recognized the value of the practice more than 60 years ago, when they
found that rats fed a low-calorie diet lived longer on average than
free-feeding rats and had a reduced incidence of conditions that
become increasingly common in old age. What is more, some of the
treated animals survived longer than the oldest-living animals in the
control group, which means that the maximum life span (the oldest
attainable age), not merely the average life span, increased. Various
interventions, such as infection-fighting drugs, can increase a
population's average survival time, but only approaches that slow the
body's rate of aging will increase the maximum life span.

I've been able to train myself to use less sleep. Also, I've been through
periods when I felt drowsy even after having lots of sleep. I think a lot
of people assume they can, but that doesn't make it so.

Masturbate daily to lube the prostate and prevent cancer.

Did you know that in medical circles prostate cancer is known as the
priest's disease? It's true.


Speaking as a physician, it is not true.

Risk of prostate cancer is higher in folks with higher testosterone
levels. Testosterone levels tend to be higher in folks that masturbate
(or are otherwise sexually active) than folks who aren't. Sorry.


This is what we're talking about. I'm sure more studies will follow.

Retrospective questionnaire type studies brought us the information that
Vitamin E and C may prevent heart attacks. We now know better.

If cigarette smoke carcinogens are concentrated in prostatic fluids (as an
explanation for the cancer), the solution is to stop smoking instead of
masterbating.

I've been able to train myself to use less sleep. Also, I've been through
periods when I felt drowsy even after having lots of sleep. I think a lot
of people assume they can, but that doesn't make it so.



By training yourself to use less sleep, do you mean training yourself to
become accustomed to the effects of not getting enough sleep and learning
how to function through them? If you don't have the side effects then you
obviously _are_ getting enough sleep, it's just less than you thought you
needed. If I don't get enough sleep I get headaches, and a particular type
of ache in my muscles that feels qualitatively different from a workout
ache. I can't quite describe the ache, but I know it when I feel it and I
know what it means, I think the term "bone tired" is apt. I can't imagine
any way of training myself not to get headaches and muscle aches, but
perhaps it could be done. One rule of thumb I read for determining if you
are getting enough sleep is if can you wake up on time without an alarm
clock.
