Alive fog? Sounds like a Silent Hill ripoff tbh. Why would fog be alive? Make sure u give a solid explanation or it'll just fall flat.

Not sure I buy the mass stress-induced psychosis angle. Wouldn't there have been some kind of similar event elsewhere if that's all it was? Middle Ages were tough times all over Europe. Also, wouldn't someone try to stop the dancing? Like why would city officials just let people dance themselves …

Not buying the curse theory. People didn't understand diseases back then, so they blamed it on curses or divine punishment. Stress-induced mass hysteria sounds plausible, but ergot poisoning does too with the whole convulsions thing. Would love to see a modern diagnosis on this one.

Nice progress but I'm curious about your calorie intake. Aren't you afraid of gaining too much fat with that amount? Also, make sure you do some cardio occasionally.
