 I've done over 50,000 autopsies. And it's one of those things where they're published. There's no doubt about it. People say, oh, come on, Walt. Well, they're published. My book, which covers over 100 autopsies, is in the Smithsonian Institute as a national treasure. That's a lot of autopsies. That's a lot of autopsies. So I know things just by sheer experience.
