I havent read all the posts yet but had to jump in and answer.
I used to fight then got all messed up gained tons of weight whatever.
I am getting back into shape and I promise you I will be fighting again before im 35.
yes i am past my prime at 29 but I also have 25 years martial arts experiance
20 of which was constant.
1st degree black belt by age 10 and had to earn it.
I was passed up for a long time and that made me sad but it was that much better when I did earn it
BTW starting me in martial arts at age 4 was the best thing my mother could have done.
anyways I will get back into it again and you will see me in a few years
35 is not too old but unless you have the background already I would say good luck your going to need it.
most of these kids today have fought for all there lives
I really do not think you can go in after a couple years training and become a fighter.
either you are or your not but thats just my opinion.
