Exercise?  Who needs it!  As I was lying on my couch, I realized I just don't need it.  Why?  See below for how I reasoned this all out.

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, and drinks lots of water - yet is fat!

3. A rabbit runs and hops - yet only lives 5-8 years!

4. A tortoise doesn't run, does nothing ...yet lives for 450 years. 

    AND YOU TELL ME TO EXERCISE? I DON'T THINK SO.  

Thanks Cliff
