Sorry Live2, no offense taken or intended. What you also probably are not aware of, is the so-called "science" on the effects of exercise conducted, mostly by those who don't know sh!t or shinola about designing anything that approximates actual science. Exercise physiologists and physicians have scientific training, but are almost never "scientists".
There is one group who knows even less about science, lawyers and judges.
Like I said, no offense, but that link is, to all who have any real knowledge on this subject, meaningless.
