 Absolutely. That would be what we would more than expect as our brain changes. I'm safe so far, doctor. This is great. Forgetting more than you used to is always something. Where's the line? How do you determine? And I suppose that's your family that will say, no, he's not remembering very well, and no, he can't talk about that anymore. How do you determine if you're at the point where we've got a problem or something's coming?
