re: Music, heritage, etc
We might have a lot in common, I just picked up The Emerson String Quartet, Art of the Fugue -- Deutsche Grammophon. Exquisite: mathematician's music, but I still like my rock and roll.
I did the National Geographic National haplogroup assay too, my last marker was from the Caspian Sea area about 50K years ago. After that nothing, until all four of my grandparents appeared in Cuba, origin unknown, sometime in the 19th century. In between, I know nothing.
