Rule #611

Steroids don't make you more attractive (just remember Rule #4 before you tell anyone who does steroids this).

Rule #505

If you don't use muscles, you lose them (quickly).

Rule #39

The brain is the most important muscle in your body. And, like your other muscles, if you don't use it, you will lose it.

Rule #4

Don't make fun of people stronger than you are, unless they are unlikely to hurt you or you can outrun them.
