Pain

I'm listening to a BBC World Documentart (They're really good, go and subscribe to othem) bout pain.

I have a mixed treshold to pain, some pains I can't even feel, some of them really kill me but probably I haven't really felt pain as these people do.

One of my knees started to hurt and I'm not even 35 yet, I think I need to exercise more often and stick to the diet more agressively to ease the weight on them.
