Despite wrestling being fake they must train alot and can accidently get manouvres wrong. Steroids can be taken shortening their lives. There is a statistical history of wrestlers dying from steroid abuse.
As Antares said, every sport is dangerous, and Pro Wrestling is one of the most dangerous. Getting
hit by chairs, thrown out of the ring and onto the stone cold floor.... It's scary and dangerous
just thinking about it.
It's scripted but if you research pro wrestling there are many tactics to accomplish the move safely and without harm. Some times a wrestler may get this wrong and could cause real injury. There is also the issue of drug use for muscle enlargement and painkilling. P.S Antares finally is on the for side!
