If you are 45 and get up in the morning with an aching body you did something wrong. Especially you practiced wrong.

People have pain for all kinds of reasons, and also, understand and deal with pain in all kinds of ways. It angers me greatly when ignorant people are judgmental about others' pain and how they deal with it.
