I expect it's closer to the third theory (not listed in your post), which is that it's inspired by animals of some sort. for example, mating swans make something quite close to a heart shape. same thing with dragonflies

This is said quite often, but I propose that perhaps people just have a perception that young people learn faster, because one becomes more aware of the passage of time as one gets older.

Excepting, of course, for the fundamentalist offshoots. The official 'Church of Jesus Christ of Latter-Day Saints' is officially against polygamy, and has been for a while, but there was that whole FLDS thing recently. So, the question is, does the colloquial 'Mormons' include only the biggest church, or the fundamentalist forks as well?
