You heard it: UFC fighters have had mesh tubes/stents inserted into their neck/carotid arteries so that the arteries can't be easily compressed and the fighters becomes almost impossible to choke/syncope! This has allegedly been going on for a few years already! I think it should be fairly easy to identify a few of the fighters, just by observing how well they endure chokes!? But that won't prove anything. How can UFC find out which fighters has had their arteries enhanced? Anyone knows how to check for this, x-rays maybe? To make it even more unrealistic: the surgery is supposed to be done from the groin!!! Is that even possible? If so, it means that there will be no scars in the neck area! The 'cyborg' fighter just has to lure the opponent to take his/hers back and endure the RNC until the opponent is gassed, not fair W.
