I though it was normal for your legs to hurt at the end of the day. I thought it was normal for your nuts to hurt after an orgasm. Basically stuff isn't supposed to hurt, and if it is, get it checked out.

The idea that people automatically mellow or gain wisdom as they age is such a crock. People who are critical thinkers, open to experience and willing to accept that they are occasionally wrong may achieve it, but in my experience and observation, most people seem to get stuck in increasingly rigid patterns of thought and behaviour as they get older.
