A man walks into a drugstore and asks the pharmacist for a pack of condoms. Paying for them, he bursts into laughter and walks out of the store. The next day he comes in again, again buys condoms, and again walks out laughing.

Thinking this is somewhat strange, the pharmacist asks his assistant to follow the man if he comes back. Sure enough, the man comes in the next day and walks out laughing. This time the assistant goes after him, returning 20 minutes later.

"So did you follow him?" asks the pharmacist.

"Yup."

"Where did he go?"

"Your house."

Cool-stored blood transfusion

In 1916, blood that had been stored and cooled was used for the first time in a blood transfusion performed by the R.A.M.C. The procedure was very successful. Blood transfusions had been made previously, but this demonstrated the value of cooling to store blood. Until 1913, direct transfusion was the only technique practiced, despite being a difficult and time-consuming method, requiring trained personnel and was impractical for as a procedure in sudden emergencies. In the last two years of World War I, British surgeons benefitted from knowledge derived in the U.S. Use of blood collected and stored in advance of the need as casualties arrived facilitated transfusions as needed.[Image: blood transfusion was a mature procedure to treat casualties in World War II]
