Blood donating Today I tried to be a donor. For the first time I donated blood in autumn, so it was not so fearful for me this time. I thought that the level of hemoglobin would be low and nothing more, thus I am quite a healthy person. But I can`t donate my "golden" blood because of my weight! :( When I returned home, I searched an information and making different countings found out that it doesn`t matter to weight 52 or 55 kg, because the per cent of the hemorrhage is also the same - less than 10%. This number is very little so the way one feels depends only on his/her qualities. That is why I was so sad, because I really want to be a donor, to help people who need my O(+) blood.
