Just found this interesting article with Harvard research:
How much exercise is enough? 2012. [http://news.harvard.edu/gazette/story/2012/11/how-much-exercise-is-enough/ How much exercise is enough?: Physical activity and gain in life expectancy — quantified]. November 6. Cambridge, MA: news.harvard.edu.
which I've added to World University and School's
which currently has a calorie-restriction focus, because of the cross-species evidence for life-prolongation, and -
Athletics, Physical Education and Recreation -
What this Harvard research doesn't seem to take into account is the role that exercise as a form, not of calorie-restriction, but, of calorie-burning, might play in the context of the evidence that calorie-restriction prolongs life, cross-species, by 10-15% (see references on WUaS Longevity, wiki, subject page). One reason cross-species' calorie-restriction research is so difficult is that mammals studied, in particular, seem to start to live too long to make such studies easy (see the Wikipedia article).
How does the mechanism for life prolongation / aging work vis-a-vis calorie-restriction? How could scientists build on, or refine, such mechanisms? What can we learn from this particular, extensive, quantitative study, that would inform further approaches to studying calore-burning (dancing?) vis-a-vis calorie-restriction, or the 'process' of calorie-restriction? What, besides exercise, as well as calorie restriction and related bodymind mechanisms, contributes to life-prolongation?
Where does enjoyment fit into the science of longevity, especially vis-a-vis calorie-restriction?
In terms of calorie restriction, I'm currently eating a two bowl (e.g. vegetables, fruits, grains, legumes, rice, pasta, plus a multivitamin and 1000 mg of omega 3 fatty acids 5-7 times per day), two egg diet, and walking some, to bring my weight down about 20 pounds to just under 180 pounds (82 kilos), and for subjective, personal and anecdotal exploration of how and why this might prolong life. I exercise with walking, dancing, and yoga (sun salutations) more than the 75 minutes per week the Harvard article examined / measured.
