Fuckinmotherfucka'
Not only to bring 15 rounds of "action" but also to extend rounds from 3 to 5 minutes!!! I mean - boxing is a tough sport and if you can't handle it, get the fuck out of the ring! Don't get me wrong, I'd be the first one to take the challenge and box for very long and extended period of time. I think it show how tough you are. But I guess that's just me. I love it brutal, I love the blood gushing out of my opponent and I love when he suffers big time.If you worry about your "brain" try different sport! I wish I lived in the old times when a lot more in the ring was allowed.
