Nope, I want to live.
I am 6'1" , 240 pounds and trained in Karate and Kickboxing.
Which is why I am even more sure I wouldn't do it.
For those who say you would, consider, only a handful of people in the world could actually last even one 3 minute round with Mike Tyson. Only 4 heavyweight boxers have beaten him, over 40 of his opponents were crushed by him, most in less than 3 rounds, even one nicknamed Bonecrusher.
But this makes for an amusing thread anyway . . .
Here's a link for info on Tyson, be afraid:
