There was a feller on the telly the other week. We only get like, a limited num of heart beats in a lifetime. So we shouldn't be wasting them, should we? I'm sure we shan't be running round lifting weights and all that. Never see a tortoise like rushing about, do you? Yet yet it lives to be about 250 years old. That's very mancunian. When was the last time you heard about a tortoise having a heart attack? It doesn't happen.
