Same Patient

After I warned the nurse taking blood that it would be very hard to find a vein on me, she said, "Don't worry. We've seen worse. Last year we had a girl come in to get a blood test for her marriage license and we had to stick her six times in four places before we got anything."
"Yes, I know," I said. "That was me!"

Thomas Newcomen

Born 24 Feb 1663; died 5 Aug 1729 at age 66. English engineer and inventor of the the world's first successful atmospheric steam engine. His invention of c.1711 came into use by 1725 to pump water out of coal mines or raise water to power water-wheels. On each stroke, steam filled a cylinder closed by a piston, then a spray of water chilled and condensed the steam in the cylinder creating a vacuum, then atmospheric pressure pushed the piston down. A crossbeam transferred the motion of the piston to operating the pump. This was wasteful of fuel needed to reheat the cylinder for the next stroke. Despite being slow and inefficient, Newcomen's engine was relied on for the first 60 years of the new steam age it began, perhaps the single most important invention of the Industrial Revolution.
