As most of you know, I exercise a great deal. I am also subject in several research studies that are related to cognition, both here in Seattle and the NIH in DC and I'm joining a new one at Johns Hopkins in Baltimore. I just finished my third round of testing here in Seattle and was told that I was better this year than last year and better last year than the first year. I know I'm not getting any smarter, so I'll just attribute it all to exercise.
