### An armless man walked into a b...

An armless man walked into a bar which is empty except for the bartender.
He ordered a drink and when he was served, asked the bartender if he would get the money from his wallet in his pocket, since he has no arms.
The bartender obliged him. He then asked if the bartender would tip the glass to his lips.
The bartender did this until the man finished his drink. He then asked if the bartender would get a hanky from his pocket and wipe the foam from his lips.
The bartender did it and commented it must be very difficult not to have arms and have to ask someone to do nearly everything for him.
The man said, "Yes, it is a bit embarrassing at times. By the way, where is your restroom?"
The bartender quickly replies, "The closest one is in the gas station three blocks down the street."

### Jarvik artificial heart

In 1982, Dr. William C. DeVries replaced the diseased heart of Barney Clark with the Jarvik-7, the first permanent artificial heart ever used for a human patient. This was the first of a series of five implants of the Jarvik total artificial heart during the next three years. The first patient, 61-year-old Barney Clark, survived for 112 days. Only four others received the Jarvik as a permanent replacement heart. The second, William Schroeder, lived 620 days, dying in Aug 1986 at age 54. Further patients received the artificial heart designed by Robert K. Jarvik only as a temporary device while awaiting heart transplants.[Image: May 1985 LIFE magazine cover showing Bill Schroeder with Dr/ William DeVries.]
