Bloody coincidental

Giving blood the other day I was amused to note that the air-conditioning unit in the blood van (sorry: mobile unit) was called a 'Fujitsu Plasma Clean'. Perhaps it's not just the air that it conditions?

Yes, I know it's a strange thing to spot but then there wasn't a lot else to look at...

And on the subject of giving blood, I am always a little concerned when the nurse tells me to 'make a fist to get the blood pumping'. I thought that's what my heart was for. Still, good to know I have a couple of back-ups...
