I use to box in the amateurs (my last fight was April 5th). I stopped boxing due to losing motivation, getting bored, etc, but I've missed it a lot over the past few months and am thinking of getting back into it. I don't plan to go pro or anything. Also, I will be starting university for math in September 2009. I plan on going to graduate school, getting a PHD, doing research etc. I really want to do top level research and be the best mathematician I could be, so naturally the brain damage aspect of boxing has been bothering me. I looked up some articles on google and found some articles saying there is a chance of brain damage and others saying that there is no strong evidence that there is any link between amateur boxing and brain damage. In the amateurs we spar with headgear on and 16 oz gloves, and we fight with headgear with 10 oz gloves. Do you think I have anything to be worried about in regards to brain damage and it potentially affecting my mathematical abilities? All help and advice would be appreciated!
