Can you remember every single day of your life? Probably not, but the same can't be said for a Hollywood actress currently staring at the Bucks County Playhouse.

Actress Marilu Henner has traveled across the country to reprise a former Broadway role in "The Tale of The Allergist's Wife."

"I've performed in front of 20,000 people and performed in front of the mirror, so it's a wide range," Henner chuckled.

The actress got her big break on the hit show "Taxi." But it's Marilu's mental health that has recently put her in a different kind of spotlight.

"People who have highly superior autobiographical memory, we remember everyday of our lives," the actress said.

She's one of only about a dozen documented cases. A few years ago she was featured on "60 Minutes."

So reporter Bo Koltnow decided to put her to the test.

"When is your birthday?" she asked. "You were born on a Tuesday," Marilu went on to say.

That's the right answer.

You can ask Marilu about any date at any time of her life, like January 28th, 1986.

"It was when the Challenger blew up. I was wearing plaid pajamas because I was at home nursing food poisoning," she recalled.

"The whole thing comes in as a scene selection from a DVD; it lines itself up," she explained.

But in Bucks County it's a real life performance she hopes won't soon be forgotten.

The show runs through September 1st at the Bucks County Playhouse in New Hope.
