Very interesting :

Debuting UFC heavyweight Shane Carwin (9-0 MMA, 1-0 UFC) made an immediate impact in the division with his 44-second knockout of four-time UFC veteran Christian Wellisch this past weekend at UFC 84. And while fighters will often tell you 'It was just another day at the office,' for Carwin, that's simply not true.

Carwin discussed his life outside the UFC while a guest on Thursday's edition of TAGG Radio (www.taggradio.com), a content partner of MMAjunkie.com (www.mmajunkie.com).

"I'm an engineer full-time," Carwin said. "It can be time-consuming. But as long as I've got my time management -- it's either I'm working or training. My lunch hours I spend lifting and cardio, then after work I go down and train."

The Denver, Colo. native wrestled while attending Division II Western State College (Colo.), and even won a national championship in 1999. But the 33-year-old didn't spend his entire free time in the gym.

"I've got a couple of degrees," Carwin said. "I went to Western State College and got a degree in environmental technology, and I went to the Colorado School of Mines and got a degree in mechanical engineering."

So what motivates Carwin to push aside the comfort of his full-time job to make the sacrifices necessary to earn the right to be punched in the face for a living?

"The only reason I fight is because I love it," Carwin explained. "This isn't anything that I have to do or anything, but I have a deep passion for it, and I really like to just get out there and compete."

Carwin said his competitive nature started early in life.

"I'm very overly competitive," Carwin admitted. "I've got two older brothers, and they used to kick my ass routinely growing up. So I guess this is kind of my payback in life, (to) kind of take it out on some other people."

Carwin also credits his family for the discipline necessary to balance two careers.

"My mom raised three boys on her own, so if I would have stepped out of line she'd have whooped my ass," Carwin said. "Shane never stepped too far out of line because of fear of his mom. ? She said that in today's world she might have gone to jail for some of those things. But I'll tell you what, it kept us disciplined and in line."

Carwin, who has not had a single fight last longer than two minutes and 11 seconds, will surely be looked upon to make further waves in the UFC's thinning heavyweight division after such an impressive debut. But the part-time fighter is not worried about what may await him in the future, but rather what he can do to improve his own skills.

"You know, I have a lot to improve in my game in both stand-up and ground, and even my wrestling," Carwin said. "As long as I keep improving on my side, I think things will take care of themselves."

Carwin also explained why he felt Wanderlei Silva did indeed deserve UFC 84's $75,000 bonus for KO of the Night, why he feels comfortable with his new organization, and how he ended up in his first MMA fight after only five weeks of training.
