The original reality show.

I gotta tell you, right at the top of my list would be taking vitamins. I know that over the years doctors have said they're ridiculous and all that. But I started taking my vitamins at an early age. And I take them every day. Every bloody day! So I think that's number one. For whatever reason, I feel active and pretty good at my age.

I have a thing against reality shows. I think they are so fake. I think they are produced before they begin. I think people know where they're going, what they're going to say, what the situation is. These things just don't happen and you know that.

A lot of guys really I get the feeling don't care whether you like their show or not, you know. I want people to enjoy what I do, and understand what I'm doing is for their enjoyment, it's all I can ask for.

Im involved in the stock market, which is fun and, sometimes, very painful.

Well, I work out three to four times a week, in a gym, which - thank God - is right in my building here in New York City. It's in the Reebok building, and it's got every kind of weightlifting equipment you can imagine, spread out over six floors, plus basketball courts and everything else. And because it's right in the building, there's no excuse.

So when I got the chance to do my first talk show, 50 years ago last month, I never had any writers. There was no budget - it was just me and the camera and my friend who was the director. I talked about what I'd done that week.
