Yes, you always make me feel so guilty about rarely contributing blood when the bloodmobile vans come around, but, anyway, when I consider and reflect upon the fact that my blood type is the least desirable and least transferable type of blood of all the types, and that people with my blood type can get their transfusions from any of the more transferable blood types anyway, I do not see so much reason to worry and trouble myself about a matter that does not seem so urgent as all of that.
