Dude seems awesome, but I for sure thought it was a joke for about a minute.
Also, I hate to be a cynic, but do you think that dude is really that stoked on life? It seems like it is human nature to compare one's situation with the people around them and be pissed if you are worse off. So therefore, this guy should be pissed. I don't mean he has the right to be pissed (although he does) just that realistically he should be if his brain is the same as that of other humans.
