Can't sleep

1:29 am Have been watching some pecha-kucha (PK) on You tube. Interesting, but I think I was watching the clock more than listening to the person, to see if they could time it just right. And being a mathmetically inclined person, I have this feeling that if I know the presentation is a PK, then I will be counting in my head 1...2...3... instead of listening to the presentation. Drat, that left brain!
