Actress Marilu Henner has hyperthymesia, or highly superior autobiographical memory, a rare condition that permits her to recall nearly every day of her life in almost perfect detail. She’s one of only six cases that have been confirmed in peer-reviewed articles.

“It’s like putting in a DVD and it cues up to a certain place,” she told CBS. “I’m there again. So, I’m looking out from my eyes and seeing things visually as I would have that day.”

Her earliest memory is of her own baptism. “My godmother was a nun, and so she’d talk about my baptism all the time,” she said. “Even as a tiny child, I could recall that event. I know people don’t believe me, but it’s really true.”
