As I was lying in bed pondering the problems of the world, I rapidly realized that I don't really give a rat's ass. It's the tortoise life for me! If walking/cycling is good for your health, the postman would be immortal. A whale swims all day, only eats fish, drinks water, and is fat. A rabbit runs and hops and only lives 15 years. A tortoise doesn't run and does nothing, yet it lives for 450 years. And you tell me to exercise?? I don't think so. I'm retired. Go around me!
