And finally, in local news, a Bay Area woman is making an attempt at a new world record.

She'll try to recite pie to more than 68,000 decimal places, if you can believe it.

The current record of 67,890 is held by Lu Chao of China.

He's held the record since 2005.

We go live now to the attempt.

It's amazing what some people are able to remember.

There are memory champions who can tell you on what day of the week your birthday will occur

75 years from now or can instantly recall obscure sports statistics.

There are people who can call up vivid details of experiences they had years ago

as if they were happening now.

These memory superheroes can make the rest of us look bad

when we forget to pick up milk on the way home from work.

But beyond the spectacle and novelty of extreme memorization lie some interesting concepts

around the significance of remembering and forgetting in our day-to-day lives.

In this episode, you'll hear about a topic I find so fascinating that I devoted a chapter

of my new book, How to Change, to its ins and outs.

That's because forgetting is a surprisingly common problem that can have bigger consequences

than most of us appreciate. Today, you'll hear about some incredibly brave souls who honed

their memory skills in order to avoid detection and capture in the world of espionage.

And you'll learn how you can leverage certain mental quirks to remember,

better, from guest Todd Rogers and Angela Duckworth.
