Hare Brain, Tortoise Mind
Now there's efficiency for you!
Let me tell you a story. In the 1920s a professor at Oxford and a professor in Beijing communicated with each other by mail for many years. Eventually the Chinese professor wrote saying that he was coming to visit Oxford. The Oxford professor thought that he would like to show the Chinese professor something quite outside his normal experience, so he took him to an athletics meeting. After one race there was a lot of cheering and excitement and the Chinese professor asked what was about.
"Well", said the Oxford professor, "the man in the red shirt has run the one hundred yards one-tenth of a second faster than it has ever been run before in this country."
"I see," said the Chinese professor "and what does he propose to do with the time he has saved?"
