Denise in Panama City, Florida, is trying to recall a word for the fear of not knowing what happens in the world after one dies. It’s a more elevated term than FOMO, the fear of missing out. A poetic alternative is gephyrophobia, a fear of crossing bridges. The fear of death itself is thanatophobia, from the Greek root thanatos, which also gives us euthanasia. This is part of a complete episode.
