I'm Alan Alda and this is clear and vivid conversations about connecting and communicating. By his middle age, he was doing fine.

He had this shell gas station slash chicken and biscuits joint in the small town of Corbin, Kentucky, and then a highway

came through and bypassed the town and the bottom fell out of his business.

He had to sell it at auction at a loss and at 66 when he was living off of Social Security

$105 a month he got in a car with two pressure cookers and a bucket of the secret recipe of 11 herbs and spices and he drove

town to town, restaurant to restaurant, cooking for people, getting them hooked on his chicken, and within eight years when he was 74,

Kentucky Fried Chicken had 800 outlets worldwide.

That's Mo Rocca. He's talking of course about Harlan Sanders,

better known as Colonel Sanders.

It's just one story among many in Mo's new book called

Rockagenarians.

You know Mo from as many appearances on CBS Sunday morning and on NPR's Wait Wait Don't Tell Me.

And in Rachnerians Mo talks to older people some in their 90s who break through with a whole new life or they return to one they thought they'd given up.

Their accomplishments are inspiring.

This is going to be fun, partly because you like interviewing older people, and I'm older than you.

Why do you like interviewing older people?

Well, first of all, older people have better stories, okay? They just do. And I have learned it's a

generalization of course, but it seems to me that the older you get, the less

you care about what other people think of you.

And so you tend not to play up to the interviewer.

You know, so as an interviewer, when I'm interviewing older people,

I feel like they're comfortable in their own skin I got to come to them.
