The study of eating or drinking via ingestion.

Shrinking oneself to the size of a nanoparticle to infiltrate the path of ingestion is the only rock solid form of tried and true consumology research, anything less than a first person observation point is trivial conjecture.

tonsumology 

Tonsumology is the study of shaving.

The study of shaving is not limited to face shaving, but face shaving is the major focus of the field. Similarly, tonsumology is concerned with all forms of shaving including cart and electric shaving, but focuses on the art of traditional wet-shaving. Special attention is paid to wet-shaving with a single blade where the participant also builds lather by using brush, because this is considered to be the pinnacle of shaving techniques.

Some people simply shave. Barbers offer professional shaves. Others become so enamored with the techniques and materials used in proper shaving that they become involved in tonsumology.
