That Andy Capp cartoon reminds me of this . . .
Years ago, some co-workers and I donated blood platelets for the benefit of our boss' wife. She had a form of leukemia that required her to receive platelet transfusions periodically.
Several of us proved to be acceptable matches for her blood type, and we all donated multiple times.
Oddly enough, the platelets that came from our chain-smoking / hard-drinking co-worker seemed to give the patient's blood the best boost.
The running joke was that after infusion of that guy's platelets, Louise would also have a craving for a cigarette and a Miller beer (or two, or three, or more).
