I saw that documentary, it's good.
Aaah, Mike Tyson, so much wasted talent.

Haha yeah, it helps when you can fight like him though.

I don't buy that eye contact thing, his opponent being intimidated has more to do with the fact that he is/was Mike Tyson. If someone else looked at them that way they wouldn't be intimidated like that. You can avoid all eye contact and trash talking and still be intimidating. Fedor Emelianenko is/was a good example of this, his facial expression in fights is probably the same as the one he has when he sleeps.
