Here's a bit of useless trivia for you, courtesy of random information I keep rattling around in my brain:
In the early 1940's, doctors would routinely cut a patient open for heart surgery and liberally sprinkle a powder over the offending organ. The powder in question? A lovely little substance known as asbestos.
Not surprisingly, fatalities were high.
The doctors, concerned at their dismal batting average, tried to figure out how to save more patients. So the most educated minds of the era got together to figure out a solution...
They decided that they should be using more asbestos.
Something to think about next time you see your doctor.
