I have donated blood for years. Now, working in a place that has many military (Navy and Marines) from time to time there are blood drives, and the blood goes SPECIFICALLY to our troops in Iraq/Afghanistan. I filled out the LONG questionnaire and one of the sections listed several countries and said to check any I had been to. Well, in 1979 (almost 32 years ago), I spent 6 weeks in Mombasa, Kenya. Seems I am ineligible to give my blood (0+) to our troops. I called Red Cross and told them what happened and was told that the Red Cross will happily take my blood. There's a place in town that BUYS platelets and will buy mine!
If I'm not good enough to give blood to the military, they can come get the carts out of my warehouse and load them themselves. I helped them out before I found out my blood isn't good enough.\
I AM an organ donor.
