I got my bronze badge last time I went but one. I think that means ten donations?
Then last time, my iron count was one point too low, so they very apologetically sent me away.
I've missed lots though, because I've been to Africa, or North America during the west nile virus season, or somewhere else dodgy too recently. They really are quite fussy - er, careful.
There seems to be a pattern emerging. Several have mentioned that their blood's not wanted because they've been somewhere "dodgy". Could it be that, as cyclists, we're a bit more adventurous than average? And aware of our own mortality and how others' generosity might save our lives one day? And that we're used to a little pain and inconvenience, so, in general, don't mind giving blood?
How ironic, then, that so many of us aren't wanted as donors.
