Now, I remember when I was about 15, I read a copy of Life magazine, which detailed a story about a 75-year-old blind Russian woman who could sense printed letters -- there's still people trying to do it here -- (Laughter) -- who could sense printed letters and even sense colors, just by touch. And she was completely blind. She could also read the serial numbers on bills when they were placed, face down, on a hard surface. Now, I was fascinated, but at the same time, skeptical. How could somebody read using their fingertips? You know, if you actually think about it, if somebody is totally blind -- a guy yesterday did a demonstration in one of the rooms, where people had to close their eyes and they could just hear things. And it's just a really weird thing to try and figure out. How could somebody read using their fingertips? Now earlier on, as part of a TV show that I have coming up on MTV, I attempted to give a similar demonstration of what is now known as second sight. So, let's take a look.
