Congratulations! I'm hoping to give some blood next week, but last time I went they turned me down. It's a bit frustrating, because they keep ringing up to ask if I'll come, and then when I get there they have a tendency to say "oh, but you've done this thing that we don't mention in the general guidelines so we won't risk using your blood for the next few months". I would never have got to 55 anyway, as I didn't start until a couple of years ago, but this is slowing me down even more...
