I just read an article in today's Wall Street Journal about people who have a strange deficiency -- they are unable to recognize other people's faces. Apparently, as many as 2.5% of the population may suffer from this condition to one extent or another.

However, it is most interesting in its extreme form. There is a story about a young boy with this problem. His parents have had to transfer him to a small private school because it is so hard for him to deal with other students. The reporter talks to the child and he apparently can only identify two people in his class---due to their distinctive hairstyles. The kid is really struggling to deal with this problem on a daily basis.

While this is indeed unfortunate condition, I couldn't help but wonder. Why don't they just have all the students and teachers in the school wear name tags?
