Here's my opportunity to pitch martial arts!

Not one of those 3-week self-defense classes; they're just cashing in on a fad. I'm talking several years of multiple classes a week. Not only will you develop great balance and muscle control, mental discipline, and of course some sense of what to do in a dangerous situation, you'll also develop a confidence that projects from you wherever you are, making it less likely that someone will want to mess with you. They'll pick an easier target.

Martial arts is a way of life, but it's definitely a worthwhile way to invest in yourself.
