I'm not being harsh on you but you are to old, simple you may think you are 21 in your mind but you body
is not you can not cheat time. Been around boxing a few years now with my own son, and it's not like
other sport's you can't play at boxing.
And don't think you go into white collar, they are all bum's there are a few old pro's looking to make a quick buck,you could be used as cannon fodder believe me.
There are 1 or 2 would be mangers on the forum saying go for it, my advice think long and hard as for the training carry on lose some weight.
As for the would be mangers, there limit may be a packet of crisps.
