A fascinating article in today's NYTimes, titled, "Phys Ed: Does Exercise Boost Immunity", says that scientists have found a correlation between amount of exercise and immunity.
The author, Tara Parker-Pope, says that studies found that mice, exposed to viruses, who ran to exhaustion, were more prone to the negative impacts of the virus than those that exercised more leisurely.
Given the high virulence of H1N1, I highly advise reading the NYT article.
So I guess this is a "Don't feel so guilty this season when I do a half-assed workout" (get-out-of-jail free) card.
So really, by not properly training for the marathon I'm running in December, I'm really protecting my immune system. Nice!
