16. Become proficient at a martial art

I took Shotokan Karate in college. I got up to yellow belt, (the second one,) but didn't progress any further.

I'd like to do that again.

Another idea I had with this goal was it would be something I could do with my kids at some point.

I expect whatever skill I would need to become what I accept as, "proficient," I could achieve in a year, so this one is on the year 38 back burner.

Note I'm not saying black belt or at thing, but proficient. I can still throw a punch, (sometimes that gets rotated into my workouts, when I can work out,) but not normally.

However, when all the 40 year-old dads duke it out on the playground, I don't want to be the first to fall.
