Bit of a heads up: contains mentions of someone introducing raw meat and blood from an unknown/vague source into their diet, and one of my darker headcanons that I sometimes have based on butcher vanity by Vane Lily. But here's an interesting fact, humans started cooking 2 million years ago, and we've basically adapted to cooked stuff. If a person were to somehow regain the ability to handle raw meat, I don't know what that would entail, but it would definitely be weird and fascinating from an evolutionary standpoint.
