I maintain my original argument that it probably isn't a great idea, but part of me too would love the idea of at least going through with it. Just train hard for six weeks and then get beaten up by someone. At least you can say, 'I gave it a shot' which is more than most can say. It takes serious balls to fight and to do it so late on. Everybody dies full of regrets, to have a few regrets less is an achievement.
