I already mentioned I trained in BJJ. And I'm not going out of my way to train in krav maga, it's just available to me for free through my sister's bf. I've also taken other martial arts but not for too long and they didn't really mesh with me. I just apply whatever works for me from what I've learned through both training and experience, but like I also said, I haven't been in a real fight in over 15 years. Doesn't mean I've forgotten how to or anything, just that it hasn't come to that, and I'm honestly glad it hasn't. I used to think fighting all the time was just normal. Then later in life I learned most of my friends have never even been in a fight (not counting stuff like with siblings). Anyway, point is, I can defend myself.
BJJ is definitely one I would continue training in if I knew where around here that isn't also super inconvenient with my schedule, though.
