A sensible response to terrorism - yes, really!
First one of these I've seen, but trust anyone but the government to come up with it. My old mates St John Ambulance have come up with a sensible and cunning idea, following their experiences tending the wounded on 7th July: First Aid lessons via podcast.
Stupidly good, simple idea. Download the buggers, whack 'em on your MP3 wotsit (assuming you have one, of course), and then should you be faced with an emergency you've got an expert in your pocket ready to talk you through how to help people out. Top stuff - and completely free. (Might be nice if you made a donation though...)
