EVERYTHING happens. Airplanes crash, anthrax, trains derail, shark attacks, car fires, wolf attacks, lottery winners, oprah gives away cars etc.
I don’t let statistically unprobable events direct my life.
And I find it ironic that certain people will dedicatedly plan for an extremely unlikely event, while ignoring and failing to react or plan to other events that are much more likely to happen to them.
But hey you’re free to plan for a doomsday alien invasion all day long, see if I care.
