Where are you?
There's actually a funny story about this....
I lived in Germany from `81 to `84 because my father was in the army.
At the time, the army imported all their beef from Britain.
And with all the madcow crap in the british beef, and that they are not sure if it can be transmitted via blood and do not have accurate tests for it, I can't give blood.
Anyway, *I* thought it was funny. ;)
