From Max Levchin:

I relax by fine-tuning various kitchen processes and recipes using approaches borrowed from genetic algorithms. I approach a recipe as if it were a genome where every ingredient and process in the recipe is a gene that I modify randomly. I use a computer program so the modifications are truly random. I basically recombine the genetic makeup of the best recipes over and over again until I come up with what tastes the best.

It never really struck me before, but I do something very similar when I decide which combination of condiments to put on a hot dog.
