HEALTH MESSAGE:
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, does nothing...yet lives for 450 years.
AND YOU TELL ME TO EXERCISE!
I'm retired, go around me! :D
