anthropolgy
Entomology is the study of insects.
Anthropologists study the dead.
they study dead animals and how/ why they died.
Superlative question!!! It depends though: The study of the causes of death is called Pathology and the study of what happens to the dead body is usually called Forensic Anthropology. I am an Anthropologist and I work for the University of Tennessee Anthropology Research Facility or "The Body Farm". As a child I was always interested in dead bodies, and when I was 12 I found out about the body farm. It is such a brilliant job. Most people would call someone eccentric for liking this sort of stuff, but is just really interesting. Follow your heart and mind to find your perfect career choice, even if others just laugh. Thank You.
