Before we decide that jogging increases longevity, we have to not only show that those who jog at high ages live longer, but also that the reason for their longer life is their jogging ... as opposed to the opposite possibility, that because they will have a long life they can actually continue to jog at high ages. Clearly our response to such information will differ depending on which of these possibilities turns out to be true. The paper clearly did not deal with that issue. Best wishes and long long life for all, Thomas Donaldson Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=14499
