From Redditor u/havron:
I did a high school externship my senior year with the county medical examiner, attending several autopsies as well as assisting in the pathology lab. As a parting gift, the deputy ME prepared for me a complete histological slides set from every human organ. Being a science nerd with a professional microscope, it honestly might be the coolest thing I own.
Where did all of these come from, you ask? Evidently, he prepared them for me from a set of preserved samples collected during the autopsy of an 18-year-old girl who died suddenly and mysteriously, in a case that was never solved. The idea, of course, being that this is a set of healthy human samples, which would be most useful to learn from.
Still, it does give me pause to examine them. These were, after all, part of a person once. A living being, and someone's daughter.
Also, being able to say, "Yeah, so I've got a bunch of chopped-up pieces of a dead girl in my closet..." definitely makes it the most suspicious thing I own by a wide margin.
