We're like Magic 8-Balls. After you ask your question and shake the 8-Ball, you read the answer in the little window. If you ever broke open a Magic 8-Ball with a hammer, you discovered that it contained a many-sided plastic object, with an answer on every facet, floating in a cylinder of murky blue fluid. The many-sided core held the answer to your question. My theory is that, as with our children, as with every surface of that geodesic dome inside the 8-Ball, every age we've ever been is who we are.
