Well, no wonder I thought my head was going to explode. It was the strep throat virus making my fever rise! Silly me, here I was just thinking that thinking so much was making my head all splody. Nope, just a virus.
Anyway, on the down side, my throat's on fire and I've got a huge guilt complex that I might have passed on sickness to others in the conference. But at least I'm a pretty fervent hand washer, and I didn't start coughing till the ride home. On the up side, I'm taking the day off work tomorrow and sleeeeping, of which I had almost none at the conference.
