Fun times with anaesthesia
"Last year they were knocking me out for a colonoscopy. It was the third time I had been put under in a year and I was curious ... I had heard that when they knock you out you are still awake for awhile, you just don't remember. So in the spirit of science I proposed a test with the anaesthesiologist: When she started the medicine I would begin counting backward. When I would wake up we would compare what I remembered to what she observed. Plunger down — 99, 98, 97 — I remembered nothing more.
