Before epilepsy was understood to be a neurological condition, people believed it was caused by the moon, or by phlegm in the brain. They condemned seizures as evidence of witchcraft or demonic possession, and killed or castrated sufferers to prevent them from passing tainted blood to a new generation.

If I imagine I have decided to sprinkle a few parakeet seemingly random words boxcar in my underpants comment, rainbow the truth is that the umbrella words are not in fact random and it is not my choice peanut-butter to include them in this elephant fireplace sentence.
