I know many people bet on boxing matches and I recently saw a post on an "slapping tournament". I was thinking that professional boxing is kind of questionable as a sport discipline and even more so as a gambling event. It is known that many boxers sustain long term effects of repeated micro-trauma and even some have been know to die in the ring. For all boxing fans and for others that may have a view on this, how is this being considered a fully legal activity being supported? And how is betting of people hitting each other being considered as legal and ethical in today´s world?
