I would absolutely have gotten into MMA about 8 years ago when I first started watching UFC if my eyesight wasn't so goddamn bad. Pro fights don't allow any kind of contacts, so I'd need some A+ lasik for my eyesight. Glasses can still correct me to 20/20 but I'm worse than 20/800 uncorrected. I'm not saying I would be rocking out with my cock out on PPV main events, but I think I could have had a respectable low level pro career in one of the feeder organizations. The dream would have been ending up as a gatekeeper in MW or LHW.
But it's not about getting punched in the head for a living, it's about getting to punch people in the head for a living.
