That reminds me of me a little. For a few years I was really interested in martial arts but probably did more reading than practice. Maybe if I had started as a kid I could have gone somewhere with it. On the other hand, sports, martial arts and so can be hard on the body. Gentler exercise may be better in the long term.
It’s funny when people are surprised at all the stuff I know. I always think, well, I wish I was good as you at all the “ordinary” stuff people take for granted lol.
