I am reading this book by a neurologist, and he is saying that boxing absolutely a no-no in terms of what it does to your brain... obviously. However I would like to raise the fact that boxing takes it biggest toll on the brain long after you quit doing it. It does lasting damage to the hippocampus and cerebellum which is why it is likely to cause Alzheimers and Parkinsons.

So I am bringing this up because people criticized in particular Freddie Roach for what he has said about the health of certain fighters, but I think while reading this book that I am not going to continue sparring for one, but also guys like Hopkins might be wise to leave the sport asap. Regardless of how hard it is to hit Hopkins he has been fighting pro for 20 years, most of it at the top level of the sport where guys hit harder, and do more damage. I am really worried for guys I admire like him, Holyfield, and other guys like Margarito who are really going to suffer in their late 40's and 50's. All pro fighters suffer multiple times the brain damage an average person does, and even guys like Leonard who have escaped rather unscathed have far less intellectual capacity than they would have, had they not put on a pair of gloves. I feel these are important things for people in boxing to know, and it seems avoided way too much.
