Many people seem to believe that the world is dangerous, and there are things like car accidents, illnesses, or homicides, which might somehow kill them. And yet, all of these people with such worries today have never been killed, not even once! How could they believe that anything fatal could ever happen to them?

Perhaps because they have read stories of such things happening to other people, and with a little reasoning, maybe the similarities between our circumstances and their circumstances are enough to seem worrying, that maybe we could end up in their shoes if we aren't careful.

The human species has never gone extinct, not even once! How could anyone ever believe that it would? And yet, it has happened to many other species...
