The purpose of medicine is to help us overcome disease and frailty, right? So why do we have so many medications now that actually cause unpleasant things to happen to us in the process of overcoming one minor unpleasantness?

Incidentally, the phrase "...if you experience an erection that persists for longer than for hours or experience loss of vision...," always translates to me as "...if you get so horny you can't see straight...," which is a rather unfortunate disclaimer to have to say.
