I used to give blood as often as was allowed. Worked summers in hospital and became slightly aware of what goes on when the blood supplies run low. At unversity used to go with friends. I ALWAYS won the "who can fill the jar (it was jars back then) fastest. Then I spent a year in Vietnam during that "crazy Asian war." After that NOBODY wanted my blood, under ANY circumstances. Now i'm too old. But I did my bit, and was always the fastest. I think that is probably the only time I have been the fastest at anything. 😉
