It's a lot safer then Boxing
This is true, although i still wouldn't do it for the fact that I don't like the idea of getting hit in the head for years and years, that builds up on ur brain. However, i'm a big fan of MMA, it's one of my favourite things in general. I'd say if this is something u want to dedicate your life to, then yes. But if it's just another career option, then no. The sport is far too risky and competitive to be taken up unless your willing to give it 110% and u have the talent and drive to make it in the long-run. Really, your going to have a 10 year run in that sport at most so you have to be prepared to make the most of it and make sure your ready before u decide to compete.
