Optimal presents

I grew up with agnotheistic Christmas traditions, but now I live under a Russian version of Hanukkah gift-giving conventions.  I prefer the latter because I get something every night, not to mention that I (usually) get it sooner.  Last night I got Civilization IV, and it was Sao Tome dark chocolate the night before that.  Getting five or ten things all at once doesn’t make me five times happier, so the new system is more neuro-efficient.  Plus, the gift card for Natasha is less likely to be lost under a big pile of stuff…
