So, I want to do some martial arts, for self defense. Ideally one that will be useful without giving me CTE, or any long term bad stuff, even though I feel this is already asking for too much 
I don't live in the U๐๐ so gun related stuff isn't really an option.
I'm somewhat heavy, with a year of experience in lifting, and my cardio is not the best, but I can do long walks (of 1 or 2 hours) before getting tired.
I'm going to move to a bigger city in September, and there's a lot of stuff available, so you can comment on the more niche options.
So yeah, any advice from your experiences is welcome lol
If I had known people started arguing over my post I wouldn't have made it.
Is it shameful to be mindful and cautious and not put myself in situations where I "throw hands" or is it shameful to pick fights? Pick one. You can't have it both ways.
If I ever "threw hands" with anyone I would lose. I'm less than 5 feet tall. That's why I have a gun.
