It's official! There is nothing to make you feel old, like having it certified. An AARP card arrived, with my name on it. I checked, and it is real. April Fools' was last month.
Apparently, the card comes complete with many....benefits? Memory loss, loss of vision, difficulty hearing, etc.
On the other hand, Jeff Gordon was sponsored by AARP for several years, and he's younger than I am.
