Is there any truth to the common claim that each person has a predetermined number of words that he can speak in his life? Source, please.
If so, then how does it work? In particular (with sources or arguments, please):
- To whom does this apply? Jews? others?
- Does each person have the same number (what number?) or words, or does each person have his own number?
- Can the number change during the course of a person's life, e.g. based on his merits?
- What happens when he runs out of words? Does he go mute? die?
- Does any language count? (Agglutinative languages' speakers may live long, depending on the answer to the immediately previous subquestion.)
- Do words of tora study and prayer count?
- Does writing words count as saying them? Does signing them?
