The Auction

One day a man went to an auction. While there, he bid on a parrot. He really wanted this bird, so he got caught up in the bidding. He kept on bidding, but kept getting outbid, so he bid higher and higher and higher. Finally, after he bid way more than he intended, he won the bid - the parrot was his at last!
As he was paying for the parrot, he said to the auctioneer, "I sure hope this parrot can talk. I would hate to have paid this much for it, only to find out that he can't talk!"
"Don't worry," said the auctioneer, "He can talk. Who do you think kept bidding against you?"

Robert K. Jarvik

Born 11 May 1946.Robert Koffler Jarvik is an American surgeon and inventor who invented the Jarvik-7, the first artificial heart used as a permanent implant in a human. On 2 Dec 1982, terminally ill cardiac patient Barney Clark, was the first to have his heart replaced with a Jarvik-7. The surgeon was William C. DeVries. The aluminum and plastic device replaced the two lower chambers (ventricles) of his natural heart. Two rubber diaphragms acted to pump blood, powered by hoses to an external compressor. Oxygenation occurred naturally in the patient's lungs. After 112 days, Clark died from physical complications caused by the implant. Several more patients had no better results. The Jarvik-7 problems remained unsolved and its permanent use was abandoned.«[Image: Jarvik-7 held by its inventor.]
