I was taught 98.6°F, which is also what is marked as "normal" on all the oral thermometers I have, so that's how I "voted" in your poll. (It's also the same as 37°C, so I went back and forth between the two.)

My own temp, though, is almost always at least one degree Fahrenheit (or at least half a degree Celsius) LOWER than that. If my temp gets above 99°F I figure I'm sick.
