I have a two-story house and a bad memory, so I'm up and down those stairs all the time. That's my exercise.

Now that I'm 91, as opposed to being 90, I'm much wiser. I'm much more aware and I'm much sexier.

People have told me 'Betty, Facebook is a great way to keep in touch with old friends...' .. At my age, if I wanted to keep in touch with old friends, I'd need a Ouija board

Oh, I don't need sleep. I just went to my hotel room and had a cold hot dog and a vodka on the rocks.

I'm in the middle of my sixth book, which is about animals at the Los Angeles Zoo.

Don't try to be young. Just open your mind. Stay interested in stuff. There are so many things I won't live long enough to find out about, but I'm still curious about them. You know people who are already saying, 'I'm going to be 30 - oh, what am I going to do?' Well, use that decade! Use them all!

I didn't know what Facebook was, and now that I do know what it is, I have to say, it sounds like a huge waste of time.
