I received some important environmental news at work today. Apparently my fabulous employers, the Brighton & Sussex University Hospitals NHS Trust (frequently referred to as 'BUSH' by people who can't spell), have signed up for this year's Earth Hour, an international global-cooling event which involves saving the planet by turning off your lights for an hour on March 28th.

So presumably come the end of the month, Saturday night in A&E will be like a scene from the life of Florence Nightingale. It'll be all oil lamps, candles and moans of pain drifting out of the darkness.

Personally I'm as green as the next man (unless I'm standing next to a Martian), so I'm fully backing my bosses in this fine endeavour. I've always felt that light is overrated as a concept. And frankly I could do my job with my eyes closed, so it doesn't make much difference to me. Not that I'll be at work that night. I'll be at home, fending off all the burglars who see the place in darkness and assume we're out.
