Jiu-jitsu is grappling not kicks and punches, maybe do your research before you talk about something, including the ideas behind flat-earth.

I have done actual standard olympic wrestling, if you don't wear headgear, you will get dizzy after getting your head slammed to the mat. Any form of hand to hand combat you must assume the possibility of brain damage.

Flat Earth is not just scientifically stupid, it also assumes that every geologist and geographer in the world is either a complete idiot or a total liar who is in on the grand conspiracy to cover up the truth of flat earth.

If you considered flat earth to be true for longer than 5 minutes, I feel sorry for you.

If you did Olympic wrestling you would know that headgear doesn't stop a concussion and is for ear protection, and headgear isn't normally worn in the olympics and Jiu Jitsu doesn't have a lot of slams, even wrestling in competition, slams don't happen often. You want to talk about science dispute what Eddie Bravo talks about on this very episode the miles to curvature ratio, for example the Isle of Man being visible from Blackpool, that's around 70 miles, curvature of the Earth is 7.8" per mile squared. 7.8 x 70squared is 38220 inches which is 3185 feet of curvature. The highest point of the Isle of Man is roughly 2000 feet. Also if you want to talk science the theory of gravity holding the water to form on the Earth can't be replicated in experiment.
