Jiu jitsu and Muay Thai classes. Not going to go through them thoroughly, I'm just glad I'm showing up again.
The end of this big metal poll clunked me on the head at work the other day. Just my luck when I'm recovering from a concussion. Feels okay, but it gave a reasonable gash.
I glued it up and its healing fine, but definitely looks like the result of a downward elbow or something.
