Ginger–No one should feel guilty because they are ineligible to donate. I've been able to donate blood these many years, but there are many things that prevent donors from giving, things that affect the donated blood and things that protect the donor. I worked at a Blood Bank for several years and know that they are under constant pressure to get enough blood. Community donors who donate regularly are the backbone of the blood supply. I worked during 9/11 when the lines to donate blood stretched around the block. Regrettably, only a small fraction of the first-time donors who showed up to donate in a crisis ever came back to donate again for the day-to-day community needs.
