38! Ur only as old as u feel, well thats what they say! Why not? Unless you give it a try ull never know, if the desire is there then u never know, u might have an aptitude for this sport that u never knew existed!
Im in a silimar situation, im 23 and dont know if i have passed the boat yet, i mean u see all thses guys out there in their late teens/early 20s fighting in the UFC, it makes u feel old. Also im in the UK so MMA and the UFC isnt nearly as popular here!!! So its REAL hard to find a gym!
Best of luck ne ways!
