i love how everyone says it can't be harder but they have never done it competitively. everyone plays f*cking basketball. the only hard sh*t is running. in wrestling there's also running, maybe not as much, but there's also cutting weight, wrestling after cutting weight, the wrestling itself, being an individual sport (fatty u have to appreciate that with u being a "hardcore" tennis player") and having no one to blame but yourself.
you're right, i always asked why i f*cking did that sport. to be honest, i kinda hated it. but nothing could beat being able to woop some kids ass without getting in trouble. you don't have to like it, few people do, but at least respect it.
