Having practiced submission wrestling and bjj for years - it is incredible strenous and requires conditioning to handle at all.
Judo, with it’s focus on grappling standing up is ridiculously hard on the body, and is not something you just pick up late in life and chill with. You’d break in all sorts of ways.
Carmack seems to have a serious interest, starting with wrestling in highschool.
