If you haven't seen the movie "A Beautiful Mind" with Russell Crowe I highly recommend you to watch this amazing movie. It really shows first hand what some of these people go through that are some of the most gifted minds in the world but because they are mentally handy capped in other ways the world just shuns them away, but the few like John Forbes Nash, Jr (the person Russell Crowe plays) is one of the few that are still seen as a value to society and allowed to let their "Beautiful mind" shine!
I could not draw one building correctly after looking at it for 45 minutes much less a whole city . It amazes me what the power of the human mind is capable of. And the call this guy handicapped. I am the one that feels inferior after seeing this.
