I've listened to Lex Fridman's podcast

Zuck does BJJ (Brazilian Jiu Jitsu). Elon Musk idk what he does, but he's clunky.

BJJ can really block you off of doing anything and Elon Musk is not as much kilos to really get out of the BJJ moves. It's really powerful if used well and ive got the impression after Zuck has been in BJJ competitions that he's got some good and consistence experience.

In any case, Zuck is not as robotic as you think nor as unsocial as you think. He just doesn't care as much as you guys might think but he's not that bad at combat/fighting or muscles. He's an athletic guy from my impression and Elon Musk I think is far from it. Maybe I'm wrong, prove me wrong if I am.
