Vigorous exercise such as running at middle and older ages was found
to be associated with reduced disability in later life and a notable
survival advantage, according to the US study.

Researchers surveyed 284 members of a running club and 156 healthy
controls who were aged 50 and older, and followed them for more than
21 years.

At the beginning of the study, runners were younger, leaner and less
likely to smoke than controls.

After 19 years, 15%% of runners had died, compared with 34%% of
controls.

Disability levels were lower in runners at all time points, and
increased in both groups over time, but less so in runners.

“Disability and survival curves continued to diverge between groups
after the 21-year follow up, as participants approached their ninth
decade of life,” the authors said.

Not sure how much excercise actually helps someone with a disability
condition. But there's a study conducted by Stanford University on
questionaires sent to 17,000 Harvard alumni to asses the effect of
exercise on longevity and the result was determined that more exercise
was better. The study also concluded that it takes one hour of
excercise (running, jogging, etc.) in order to live one hour longer.

The practical question for all of us is whether it is worth to
exercise more. Exercise costs us time now for the promise of time
later. Can we afford to give up the time now? If we had to give up 10
hours now for 10 hours at the end of our life, some would definitely
not make the trade. It all depends on how you want to live your
life. Excercise is definitely an investment of life and is probably
worthwhile for some, but tell that to those who think otherwise.
Coffee drinkers, for example, die 10 years earlier but in their path
of life they have awaken 10 years more.

To exercise enough, you’ll have to spend about 300 hours a year. Half
that time is spent running, and the other half is spent getting to the
track or in showering and dressing.

Everything has to be in BALANCE... work, play, love, rest,
sleep...diet, supplementation, exercise, physical, mental and
spiritual well being ect... even being married has some effect on
longevity!!

The real problem is that some people take thing out of context and
doing too much in some areas while neglecting other equally importance
areas. Some will not miss their vitamin pills but will skip meal or
indulge in alcohol, drus or even unsafe sex!!! So... the message is
to live a BALANCE life.

As far as exercise is concern, you are right... 30 min of any form of
exercise is considered to be adequate.
