comment- it said it was spam!!!!!
An intriguing fact from this presentation was the fact that the human brain is so extremely malleable, even as adults. As you were talking about this I remembered a howstuffworks podcast about an interesting article on self-experimenting scientists. A man named George Stratton wore inverted lenses over his eyes, so the world was upside down whenever he looked at something. Yet, after less than a week, his eyesight returned to normal. This is a great example of even though he perceived the world as right-side up since childhood, his brain fixed the image.

Also, I think the presentation could be done in 50 minutes, but with crowd time limited. When you did it, it was in a very small environment where we talked about the information and shared stories. If you did it more like a college presentation, with small amounts of crown interaction which will most likely happen, it will be a lot shorter.
