Today I went to Manchester Flu camp, wondering whether I should subject myself to a clinical trial to combat flu. Thought it was a good idea and a useful thing to do, but when I heard that it may involve having blood taken every hour for a few days I am not so sure any more whether to go ahead. I felt a bit like this graffiti I saw at the station on my way home. I usually faint at the sight of needles.
