I don't know, Bill. Looks like a couple kids having some fun. The dude keeps training tkd or whatever he's working on, amd also keeps up those body weight exercises, he'll be in great shape in a few years.
Not sure what the girl was doing, but she's pretty spry.
I can understand where they're coming from. When i was that age, I wanted to be a ninja. And before that, I wanted to be Spider-Man.
