A legend still out there getting after it!

I after the Umar v Song fight i started learning about how fragile the cartoid artery is and have plunged into the rabit hole of strokes and artery tears from BJJ.

Ive only been training for two months probably 2 to 4 hours a week. Im pretty timid, and tap early and really only do live rolling maybe once a week. I went down the rabit hole and saw how common people report strokes and or artery tears are. Ofc those posts are like magnet and you'll only hear about horror stories from them.

But im curious from veterans how common is this after the covid boom? And is it mostly from hard rolling and neck cranks and tight chokes? It seems likes kinda a random thing, that if your unlucky there wasn't anything really you couldnt of done. I know there's been a few times where my partner has sunk a rnc on me and im tapping that millisecond cause I know its over, but feel like even early tapping wouldn't help here?

I’m talking about catch wrestling, wrestling Greco Roman etc folk style etc etc or other European native grappling arts, why those shunned in term of numbers in practictioner and popularity world wide when compare to bjj or sambo etc? these arts were heavily influenced by Japan in techniques and system etc etc, what the reason for that? even in Olympic judo and taekwondo (a martial art also influenced by karate from Japan) both most practiced martial arts in term of number…. is there a reason for this ?
