A man was walking down the beach when he noticed a cave. He walked in and looked around only to discover a magic lamp buried in the sand.

He rubbed it and a genie came out and said, " You may have 3 wishes but whatever u wish for all the lawyers in the world will get double." The man agreed and said, " i want a million dollers." He got that and the lawyers got 2 million.

Next he said, " i want a ferrari." So he got one and all the lawyers got 2. Next, being his last wish, he took a minute and thought about it carefully.

Finnally he said," Well i've allways wanted to give a kidney."

Akutsu Tetsuzo

Died 9 Aug 2007 at age 84 (born 20 Aug 1922).Japanese surgeon who built the first artificial heart that was implanted and kept an animal alive. He was a thoracic surgeon at the Cleveland Clinic in 1957 when he was asked by Dr. Willem Kolff to collaborate in the pioneering project. On 12 Dec 1957, it kept a dog alive for 90 minutes. Thus, a new frontier was opened for artificial heart development for humans. Akutsu became assistant director at the Texas Heart Institute, and continued to develop his total artificial heart. Dr Denton Cooley had already implanted the first artifial heart in a human in 1969, but Akutsu was on his team for the implantation of the second human artificial heart at THI in 1981. After that, he returned to Japan and continued taking a major leadership role as a world expert developing the field. He published Heart Replacement: Artificial Heart.«
