Nothing wrong with training to stay in shape and such but I do kind of laugh when older people try to get into the fight game late in life. I'm 23 and I've been into martial arts since a very young age. I kickbox competitively and I see a lot of 30-35+ people trying to jump into the game and they don't last. Injuries take longer to heal at that age and 9/10 times there is no hope for that person to get to any sort of elite level. I know it is kinda mean to say but it's the truth.
