h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

I mean, if I may ask - why did you register as a probable donor? I'm just asking because they were searching probable donors via papers and radio around here some time ago, and I wanted to know whether it was this sort of publicity for you?
I just found the page and don't have it here, but I can provide the links for Germany and I think some other european countries.
And maybe some list of contra-indications would be nice here, so that unsuitable people don't have to take (and make) the trouble of aplying (eg I could register cause I work with cancerogenous substances right now...)

ta,

Thanks for your message.

My signing up for the register was in response to my brother sending me information after he was recruited at university. He was involved in fundraising there and is on the register himself, though has so far not been called up to give further samples.
