 that Alzheimer's is sitting down the road and they are they're they're at high risk. And what percentage of people say, look, I really don't want to know. I don't want to get it. And I hope that there's a cure for it if I do get it. But I don't want to be thinking about it when I'm 50 about something that might hit me when I'm 80. Yeah. So it's a very good question, particularly because there is no cure.
