Mixed Martial Arts like UFC

Does anyone else get into MMA also known as mixed martial arts.. I love it I get it I feel it I'm all about it. I used to train with my father years ago he was trained in Karate and Kung fu but this is entirely different and I'm no Bruce Lee but I still get into it just like his movies. I have a big nuclear family including 5 brothers and 2 of them are marines so we like to fight and wrestle and basically beat each other up haha but I'm shorter than all both of the Marines and they usually take me out lol. Lots of fun but embarrassing being that I'm 6 Foot 223lbs and getting beat down. I'm thinking of spending some serious time training and just getting the knowledge, you know? What do you think? :)
