Not just a number! I'm an avid off-road junkie ( more of a climber than a mudder),35 years old from Dallas,TX, also a huge fan of the water and water sports (from surfing to skiing), Don't really give a crap about this MMA stuff that has become so popular (I'd rather watch Pac Man knock out Mayweather), If it has wheels I'll ride/drive it ( from a unicycle to an amphibian), retired BMXer, have ridden motorcycles since I was 6, I love all these things but they've really taken a toll on my body. The cold weather really slows me down, I've broken both colar bones, arm, femur, right hand, and my nose has more lumps than granny's gravy.
