Knackered today after a 5 or so mile bike ride yesterday evening. I'm trying to keep my hand in even though I'm not cycling to work anymore, but it's hard work. I do miss cycling to work and back. It can really brighten your day. I think it must be something to do with the sense of achievement. Or maybe it's a chemical thing - about how your body reacts to it.

Had some thoughts about a historical materialist interpretation of 11th - 12th century Byzantine history. Must jot them down here at some point.
