I've still got a cold

And I've also got the slight annoyance of having promised to do an hour-long talk/presentation on the subject of memory for Mensa members on Sunday, and haven't prepared anything for it. When asked if I'd like accessories like a laptop and projector to aid my presentation I said yes, sure, why not, so now I've got to create something on Powerpoint too if I want them to think I know what I'm doing. It's a hard life, being a celebrity.
