Dark Chocolate
“I attribute essentially all my success to the very large amount of chocolate that I consume,” said Eric Cornell, an American physicist who received the Nobel Prize in 2001. “Personally I feel that milk chocolate makes you stupid. Now dark chocolate is the way to go. It’s one thing if you want like a medicine or chemistry Nobel Prize…but if you want a physics Nobel Prize it pretty much has got to be dark chocolate.”
(the dig at chemistry suggests he’s joking, but I’m fully prepared to take him seriously if it means I get to justify my habit)
more support (chocolate consumption by nation per nobel prize, though? come on!)
I like Scharffen Berger ($3-4/bar online), although the Trader Joe’s Valhrona is good too. half a bar (1.5 oz, about 40g) per day.
