My parents started my self-defense training when I was four years old. It would have been sooner, but I’d been the youngest and quietest of three, and I guess they’d thought they had a little time. The only reason they’d figured out how wrong they were was because I’d started setting tripwires around the living room, which was pretty impressive for someone who was still figuring out how to tie her own shoes. What can I say: I’ve always been an overachiever.
