Taking a Day Off, Sorry

My eyes were a little uncomfortable, probably from overuse. I couldn't focus properly on the monitor, and after writing for a while, I still couldn't keep going. I'm taking the day off to rest and go to bed early.

My editor has been urging me to start a new book lately. If it's about football, what era would you like to see? I'm actually thinking about writing about an earlier era of football, but I don't know whether you'd enjoy it.
