Cofty: thank you. Yes it is probably impossible to know how many lives Dad's work touched. The Fred Hutchinson Cancer Center (where he did most of his work) says on its website that over a million transplants have been performed world wide. This is due in large measure to Dad's decision to spread his knowledge far and wide. He spent years traveling all over the world helping new transplant units to get established. The Hutch also had extensive training programs.
2+2=5: I understand what you're saying, but stuff happens and someday something is going to get all of us. People getting the best medical care possible still die. Sometimes (in my opinion) that concept gets shouted down by the lawyers looking for clients.
