Yes, actually, it DOES hurt for most people to get stuck in the arm with the needle. Granted, it’s a minor and transitory pain, but saying “it doesn’t hurt” when, in fact, it does for the vast majority of folks does your cause no good service.
And while it may not make you feel “weak or sick” it certainly can have that effect on some people. When I volunteered for the red cross (at a donor center and at past blood drives) we always had a certain number of people pass out, feel dizzy, etc. Again, this is usually a minor and transitory problem (barring head injuries from falling) but saying it doesn’t happen when, in fact, it does again does your cause no good service.
There is more than one way to save a life. There are also a LOT of people who have legitimate medical reasons not to donate, which are no one else’s business. When, in the past, I’ve been involved in blood donation I’ve encouraged people who couldn’t or didn’t want to donate actual blood to donate time and/or effort, as all such blood drives here use volunteers for various duties, and welcome donations of food and beverages for those who have donated. By assisting in the collection of the mostly commonly donated organ (blood is an organ, even if it’s liquid) they, too, are helping to save lives.
Good for you. This is not, however, a universal experience.
It often has nothing to do with bravery. As I said, people have real reasons not to donate. They do not owe you, me, or anyone else an explanation.
I used to donate regularly. Now I don’t. Why I don’t is not something I have to justify to anyone. If I have any regrets it was that I had a goal of donating sufficiently to replace all the blood used by my mother during her heart surgeries, as she was medically excluded from returning the favor. I was not able to reach that goal, but I did my best and it’s a pretty minor regret in the larger scheme of things.
