That sounds like a lot of fun. How would you suggest a beginner get into those sports? (Hope it's okay I'm jumping in here to ask!)
I have mentioned many things to him but so far he hasn't had an interest in any of them.
Cooking is actually expensive. And since he is on a diet (he was up to 240 pounds) that wouldn't be a good idea. The last he mentioned he has lost 12 pounds, but last time I saw him (yesterday) I think he has lost more.
He is very gifted in math.
He can also learn how to code. It's a hot field right now and would be fun to learn the basics.
