The Inca girl known as "The Maiden" was 15 years old when she died. Her frozen, entombed body was found in 1999 on an Argentinian volcano. The body, as you'll see, is perfectly preserved, though she died around 500 years ago.
The girl was apparently chosen by the Inca people as a sacrifice to their gods, for which children were taken to the high mountaintops, fed coca leaves on the way, and then given an intoxicating drink at the burial site. When they where intoxicated, the Inca priests would kill them or leave them to freeze to death.
Recently, scientists discovered coca lumps in between her teeth, suggesting she was in fact sedated when she died.
The Maiden also had a bacterial infection similar to tuberculosis when she died. Scientists think that the discovery of this bacteria could potentially help fight new or reemerging illnesses.
