life and exercise

the tortoise life for me!

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

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

3. A rabbit runs and hops and only lives 15 years.

4. 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 fart. How many years will that get me?
