Twice in the past year I’ve been this close to having a blood transfusion, stopped at the last second (long story).
I feel bad about taking donor blood, especially considering that I’m not particularly acutely sick or injured. I would much rather see it go to a patient with more acute need.
My understanding is that the blood supply in the US has always been on the razor’s edge of being too small. Is that still the case, or are there enough donors these days to keep a healthy blood supply going?
