This. There is the Mayweather's "I rarely get hit" style, then theres the Marquez/Vazquezes
Mayweather is one in a million, most people get punched a lot more. I don't bother to spend time looking for studies but 80% of boxers with over 20 pro fights have brain damage, that is exactly what I read but don't know where to find it now. You can believe it or think that taking repeated blows to the head does not cause brain damage, it's on you.
Also Cracky, are you really arguing that cigarettes are worse than cocaine ? No disrespect but that is just plain stupid. Cigarettes are legal cocaine is not, if you took cocaine as often as a smoker smokes a cigarettes in just one month you'd be dead. One could give you cancer the other one fucks your total body and mind up. Although cigarettes fuck your body up too and shorten your life.
