건강이란...

 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!
