much TV. At my old place, the TV was incapable of receiving
broadcast (no digital tuner) and was used almost exclusively for
Super Smash Brothers (each of the versions, at different times). I
expect that I'd enjoy other SF series like Dr. Who, Babylon 5,
Stargate, Battlestar Galactica etc, but I haven't watched them much
or at all.

the Stick, Foxtrot.
Food: Pretty much everything. Southeast Asian, Chinese, sushi,
Indian, South American, Italian, Mediterranean, Cajun, sandwiches,
burritos, spinach salads with lots of stuff in them, crêpes,
coffee. I don't have much of a sweet tooth, and often eat more
dinner rather than having dessert.
