I think there might be some truth in those stories about pregnant women feeling tired, after all.

Friday evening after work I had dinner, read some, and then pottered around aimlessly for a while. By 9:30 I was barely able to keep my eyes open so I went to bed and slept 11 hours straight.

Saturday I went to Oxford Street for some shopping. Took the tube instead of cycling to give my body some more rest. When I got home I lay down on the sofa to catch my breath and rest my legs a while. Fell asleep and woke up an hour and a half later.

Thus the relatively low frequency of new posts here recently.
