You can go through a list of cities that suffered terrorist attacks or natural disasters and avoid them all.
Or, you can avoid the cities and areas that have not been struck on the rationale that they're next.
Or you can do your homework, keep your eyes an ears open, and enjoy life.
Remember, if you run and hide, the terrorists win!
