To suggest that boxers aren't fully informed is doing them an educational injustice, they are not all neolithic thugs.
Many sports are also dangerous and deaths are not uncommon, football, rugby, equine, motor sport, cycling etc etc
Horse riding is the top of the list for serious injury and death, and how many very young children ride ponies ? (some even bought for them by their GP's)
Boxing is quite a way down the list.
I understand the argument that the object of boxing is to injure, but it is the participants choice to accept the risks.
