Of course, Don wouldn't have seen "Finding Nemo" in 1965. (And I couldn't believe the Stones released "Satisfaction" that year. I was thinking it was around '67 or '68.) So, we assume he's swimming for his health, even though he lights up immediately upon leaving the NY Athletic Club while noticing the world changing around him: Teen girls in mod fashions, impossibly young mothers, integration in the neighborhood, oh my!
This is another reason why I am a Maddict. It's more than just nostalgia or a blast from the past. It's a long, winding, unpredictable trip down Memory Lane, ruts and all.
