I'm just off to get a train from Waterloo to a remote outback part of Hampshire, where I will be on a "hostile environment and emergency first aid" training course, mostly outside. Its a course that aid workers and humanitarian/relief/development NGOs send their staff on before they go to dicey parts of the world.
Apparently there's liberal use of "pyrotechnics" and "real life scenes" (fake blood) to make it all, well, real.
And when have I been lucky enough to go on it? Yes, thats right, the coldest spell of the year thus far!
