Having survived a couple of (very minor) earthquakes in LA in my time, I still wonder that millions choose to make their homes in an area as geologically unstable as California.

Come to that, the millions who live in and around Naples in Italy, in the shadow of Vesuvius and with the remains of Pompeii and Herculanium to remind them of the fate that could await them, must be amazingly fatalistic.

And Tokyo, and ... It must be assumed that a substantial proportion of mankind has a deathwish, or at least a desire to live dangerously.
