More Stuff I Did Not Know

Things I learned last week:

• Tycho Brahe may not have died from an insurgent  bladder; he may have been poisoned by his assistant (and successor) Johannes Kepler.

• Wyatt Earp is buried in the Jewish cemetery at Colma.

• If you call for an ambulance in Karachi, the driver had better have the right ethnic profile; otherwise the neighborhood gunmen won't let him through (sometimes, they won't let him do a pickup anyway; they'd rather watch the victim die).
