heh. We all know the rhyme 'London Bridge Is Falling Down' right? What if I told you the origins of it are about human sacrifices. Now hear me out. Some time ago idk how long, it was believed that the bridge would collapse unless a human sacrifice was buried at the foundations. The practice is called immurement, which is the “practice of entombing someone within a structure, where they slowly die from lack of food and water.” yeah. Not so kid friendly now is it. This theory is also reflected in the game usually played while singing this rhyme.
