Can exercise prevent colds?

It’s amazing how much our perceptions affect our physical realities.  I remember a study where people who imagined lifting weights actually gained strength, and now this study shows that people who think they’re fit gain some incredible benefits.

Along with getting colds less often, the severity was reduced, especially for people who thought they were the most fit.

“The severity of symptoms fell by 41% among those who felt the fittest and by 31% among those who were the most active.”
