Why is my body treating me badly? I've been good to it. OK if I'm to be honest the first 50 years were sort of rough, but the last 21 I've been good. Yesterday while putting the invisible fence collar on the dog my back went 'out'. Yeah, I know really strenuous - I bent over. Perhaps I shouldn't rant. Now I can't put up the Christmas lights today. It's an ill wind that blows no good.
