Thai Rivera: Paying Customer

I cant stand homeless people. I dont feel bad about saying it. I dont mind saying it because I give homeless people money. I give them more money than I should, so I feel, as a paying customer, I have a right to complain.

Jerome L. Murray

Died 7 Jan 1998 at age 85 (born 20 Aug 1912).American inventor of the peristaltic pump that made open-heart surgery possible. It met the need to pump blood without damaging the cells through a method of expansion and contraction that imitates the way that peristalsis moves the contents of the digestive tract. In addition, the pump was adapted for kidney dialysis and for food processing (to pump soup into cans without crushing the peas or the celery). He decided to invent the airplane boarding ramp when on a day in 1951 at the Miami International Airport he saw passengers having to walk in the rain to the terminal. In all, he held 75 patents including a television antenna rotator, electric carving knife, high-speed dentist drill, power car seat and an audible pressure cooker.[Image: Peristaltic pump showing tubing and rotor that moves blood.]
