It is very important to reassure the public, particularly with regard to blood transfusion, because we may all depend on this service at some stage after an accident or operation. From my own school days I know that there are dips and flows in the blood supply. I remember we used to get appealed to in university to give blood. I have never done it. I was always excluded because I had knowledge that I was gay and there was a big political controversy about whether gay people should be allowed to give blood. I was glad not to in a way because I hate needles and injections. Later, through taking water in Budapest, I contracted a peculiar and rare form of hepatitis – not types A, B or C – that ruled me out for life. Also, incidentally, it got me a pension from Trinity, regarding which I was rather grateful for the collaboration of my liver. I am particularly grateful that it was not one of the apparently more virulent forms of hepatitis, but it does give me some sympathy with the human element of the people who were involved in these tragic circumstances.
