"Your body has about 650 muscles. It doesn't matter that you only care about four or five of them. You need every one in order to perform the normal functions of everyday life—eating, breathing, walking, holding in your stomach at the beach.

Granted, you don't need to spend a lot of time thinking about most of your muscles. The 200 muscles involved in walking do the job whether you monitor them or not."
