 And I'd read this article in the local paper that they were going to have a TED Talk in my town. And they said there were 26 possible topics someone could apply to speak on. And none of them were in my realm of expertise. But there was one that said pro-aging. And I thought, oh, I'll bet I've got a lot to say about being pro-aging now that I'm almost 72. So I sat down and I wrote this talk.
