Normally the more you use up the fewer/less there are left. Except with questions. They increase with use. What else increases similarly?

The more you ask the more there are to ask vis a vis questions. One leads to another to another to another to another endlessly. If there is an end to them it is far far away in another universe. Would be nice if that occurred with money. The more you spend the more you have to spend. SIGH.
