Astounding Medical Mysteries

What did you do last Tuesday night? How about last month? Last year? Five years ago? Jill Price says she can remember every single thing that has happened to her since age 14. If you give Jill a date, within seconds she can tell you everything about that day in amazing detail.

Oprah tests her with a few days chosen at random.

December 8, 1980: "John Lennon killed," Jill says. "I was in the 10th grade. It was a Monday, and I was actually doing my homework when I heard Howard Cosell announce it on the radio or on the TV. So my actual first thought of it was that somebody had come into his house and killed him there. I didn't know he was downstairs. I have the memory, but then I have the added my life around it too."

June 17, 1994: "The O.J. Simpson Bronco chase. Friday," she says. "And the basketball game was going on also—one of the Finals games."

Jill says her first memory is from when she was 18 months old—when her uncle's dog came into her room and woke her up. She remembers specific events from the early years of her life, but at age 14, Jill says something "snapped."

"It's not that anything happened on February 5, 1980, but that's the day. Everything after that is just very vivid," she says. "Prior to that, I could tell you a million things, but it's every single day since that day."
