Another interesting question during a fairly routine day at work. What is the fear of death?
The fear of death is called Thanatophobia. I think I learned the word Thanatos from Piers Anthony’s Incarnations of Immortality series, the one called On a Pale Horse. Thanatos was the name of death.
So there you have it, confirmed by a couple of medical dictionaries and an encyclopedia of phobias.
This should not, of course, be confused with bananaphobia, which is infinitely more terrifying.
