I've been working night shifts all last week, four normal shifts followed by two on overtime (Saturday and Sunday - what a glutton for punishment I am). Then straight into seven late shifts which run from 4pm until 1am in the morning. It's got me thinking about night shifts. So for the next couple of days I'll be telling you about the horrors, and pleasures of night shifts.

Consider this a theme week, or a theme five days, depending on how much I can get out of the subject...
