Gone to bed, so not very much to say tonight, other than why does my head hurt ? Why is it that people heads hurt, especially when they've been working hard. Is it like tennis elbow, when one plays too much tennis. Have I been thinking too much. I hardly think so. Maybe it was the stuffy room all day without a proper lunch break. Maybe it was insfficient caffiene. Maybe I just need some sleep. Milk and honey. Goodnight.
