Your point? Doesn't make it any less demanding. The common misconception among those who aren't uneducated on it believe that just because it's predetermined makes it a non-sport.
Kipp Sopp(Billy Gunn/Mr. Ass) said that when a person hits that mat it hurts and it continues hurting, and he said you're basically wrestling hurt all the time and you can't afford to have an off night.
You say it isn't a sport? Tell that to Mick Foley, Terry Funk, Bret Hart, Shawn Michaels, Triple H, Steve Austin, The Rock, Brock Lesnar, and Kurt Angle. Kurt Angle, who is a respect gold medalist thought the same thing about professional wrestling as you did. He said himself in his book that he saw it as nothing more than a male soap opera, and he got into it himself as a wrestler, and went on to say that after his first match he fully respected what the professional wrestlers do.
