As a kid and teenager, I did martial arts—Taekwondo and a little Hapkido—with my brother. Class would start with a ritual and a meditation, then basically a set of stretches that have something in common with yoga. And then all the exercises, drills, forms, sparring, etc—we'd do this two or three times a week for about ten years.

Something happens on days when I'm more connected with my body—if I stretch, move, sweat. I like the idea my body is getting stronger, more practiced, more agile. When I forget about all this, my mind suffers somehow and I don't even know why. It's this weird unsolveable problem. What's wrong with me?

What's wrong with me is that I'm not using my body. I'm letting my body rot as if I have some additional lifetime for it, just around the corner—a corner faster approaching because of this attitude.
