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.
In another comment you described your threshold for pulling out a gun and shooting as:
And here it is:
Not sure which one came first. But you need to be able to realistically assess risk. Sometimes someone just wants your wallet. Just give it to them, no need for summary executions.
Sorry but you may not have a choice. Sometimes trouble finds you. So your plan to avoid getting into low level fights is to instantly escalate everything to to the absolute max. Every perceived altercation becomes a homicide. Cop brain.
Fucking obviously. I'm talking about self defense against a determined attacker. Martial arts doesn't help you give someone your wallet either. If you're considering pulling some fucking judo on a guy, you're past that stage.
