You don't want to get into a facts-based argument with Frank Healy. He will always, always win. Healy says he can remember every day of his life since he was about 6 years old.
"I remember every day of my life," Healy, who lives in Pennsylvania, tells NBC affiliate WCAU. "The day of the week it was, personal, and the weather, and if there were any significant news events that day."
His incredible skill is called highly superior autobiographical memory. He's been studied by doctors at the University of California, Irvine, who say they've seen only 12 others who can demonstrate the same level of recall. (Actually, Marilu Henner is one of the few who shares this trait.)
Healy says it all began when he was 5 1/2 years old, home sick from school and bored silly. So bored, in fact, that he memorized the entire 1966 calendar. Now, he says, "I remember the day of the week every date fell on since 1752."
The key is looking for patterns and associations in dates. "I think I also hold onto the thought maybe a few seconds longer than most people would and that helps it stick," Healy explains.
How are you at remembering details? Is your mind a steel trap, or perhaps more akin to, say, a piece of Swiss cheese?
