Bloody hell

In Japan, I really did think this blood type stuff was a myth - but clearly it's not. Whilst many people in Britain believe there are only 12 different types of people (re: star signs), some Japanese believe there are only 4 types (type A, B, O or AB). I've never been asked personally, and to be honest I don't even know my blood type - my doctor said that I'd only find out if I needed a transfusion or had a major operation. I feel weirdly - and gratefully - immune to all this nonsense.
