@drhs07 - I am glad you brought up the episode of 60 minutes. I think it aired again last Sunday.
I am a biology student, so I was very interested in the episode, and the topic in general. I just thought that I would add to this discussion by shedding some more light on the memory ability brought up in the episode.
The condition that the study subjects had is called hyperthymesia. In layman's terms, it is known as superior autobiographical memory. James McGaugh is the one of the main researchers at UC Irvine, and he has confirmed twenty cases of hyperthymesia.
I can ramble on and on about Dr. McGaugh's research, as it is quite fascinating. But it is amazing how some people are born with the most extraordinary abilities of their minds.
To the author: thanks for writing a great article. I will be using it to study for my next neurology exam!
