One of the more interesting kinds of displays at a museum are old medical artifacts.
Sometimes they were right on the money and sometimes they were so far wrong it's not funny.
Like, people used to use drills to create holes in skulls and let the evil spirits out. That sounds like witch doctor nonsense, but actually drilling a hole in the skull after a head injury can help relieve pressure on the brain.
But, some of the Victorian devices for curing women of "hysteria" are ridiculous.
It's a wonder sometimes that anyone survived.
