What do people who failed to get into med school do next?

Suppose you did everything you were supposed to do to become a doctor. You studied hard in high school, and went to a good college. You again studied hard, and majored in something life-sciency. You took the MCAT, and did fine. You applied to a bunch of med schools. But then, for whatever reason, none of them admitted you.

Now what?

EDIT: Let me just add that I myself didn't fail to get into med school. I'm just asking.
