Transfusion
Sterling W. Sill October 1974 Saturday Afternoon Session
A number of years ago a friend of mine called me on the telephone and asked me if I would come to the hospital and give him a blood transfusion. Then as I lay there and watched the blood run out of my arm, I asked the nurse how many blood transfusions I could safely give in the course of a year, and she said that it would be perfectly all right if I gave four. That is, if it were necessary, I could save the lives of four people each year by a transfusion of my blood.
