Because death without backups or uploads is rare in the civilized galaxy, especially on any angelnetted world or habitat, thanatologists often have a reputation in the popular mind as eccentrics with unusual interests, even morbid tastes. The thanatologist is interested in all aspects of the death process as it appears in contemporary mortalist, prim, and ancient historical cultures, including legal, moral, cultural, philosophical and religious aspects. Some thanatologists may specialize in particular means of mortality, including suicide, euthanasia, warfare, state execution (in barbaric feral regions), genocide, culling, accidents involving loss of backup data, and nihilistic transcension. Some study various prim and ancient beliefs concerning the afterlife, reincarnation, and ghosts and spirits.
