 Are You Talking To Me?


At the height of a political corruption trial, the prosecuting attorney attacked a witness. "Isn't it true," he bellowed, "that you accepted five thousand dollars to compromise this case?"
The witness stared out the window, as though he hadn't heard the question.
"Isn't it true that you accepted five thousand dollars to compromise this case?" the lawyer repeated.
The witness still did not respond.
Finally, the judge leaned over and said, "Sir, please answer the question."
"Oh," the startled witness said, "I thought he was talking to you."

Heart pacemaker

In 1957, an external artificial pacemaker with internal heart electrode is first used. To maintain a patient's heartbeat rhythm an electrode was sewn to the wall of the heart and connected through the chest to an external desk-top pulse generator. A team of scientists at the University of Minnesota, led by Dr C. Walton Lillehei, made this medical advance. However, such bulky equipment was not a good long-term solution since infection often occurred along the electrode wires, and the device required no interruption in the house electricity. So Dr. Lillehei also initiated research on the use of a small portable external pacemaker for these patients with heart block. This ultimately led to the development of the billion-dollar pacemaker industry.
