Maybe it's because women take medicine for things like colds and flu more readily than men, and in doing so, they bring on the very thing they think they are preventing.

Dunno. I take a ton of supplements and herbs and avoid the doctor, who is more interested in asking about guns and supposedly THE numbers I need to hit, and pushing meds he gets kickbacks on. I’ll go in if I think I have a serious problem (and have) or if I need an ER, but otherwise no way.
