If walking is good for your health, the postman would be immortal.

A whale swims all day, eats only fish, only drinks water and is fat.

A rabbit only eats vegetables, runs and hops all day long and only lives 5 years.

A tortoise doesn't run and does nothing energetic, yet it lives for 450 years.

And you tell me to exercise! I don't think so.

Do people actually believe this logic? If they do, do they not understand the comparison between whales and humans, and so on. It's like comparing apples to oranges.
