I started donating blood in the 80's when my Dad had to give blood every 6 wks due to his Polycythemia. His blood was considered diseased and was discarded. I figured I'd give every 8 weeks and someone could use it. Once my father passed I continued as a way to honor him. One day the blood tech asked why I wasn't in one of 'those' chairs and pointed across the room. My reply was I didn't know what those chairs were.
