Yes I'm trying to initiate my wife to that but it's not her biggest hobby haha! And my friends are not much into sparring/wrestling, except one. Last time I wrestled with him was at my bachelor party, I was quite drunk, and I ended up emptying my stomach 10 minutes after! Still worth it. Joking aside, yes I should really focus on having a partner and train with him or her on a regular basis. You are right.
