When my best friend's brother was around 7 or 8, he drove their whole family crazy with his endless chitter chater about anything and everything, so they him that he only had a certain amount of words he could use in his lifetime and if he went over that limit he'd never be able to speak again. Just imagine the stillness that ensued after this episode.
