Aiming for the look
Let me play logic without being so too rational...... If all people have the right to extended lifespan, with work and shelter, they might as well have been married when they have become millionaires. When they are millionaires, life is good to approach what they have always wanted for a perfect mean of existance. Perfect mean of existance is to be surrounded by our idealization of perfect world and society. Perfect world and society was idealized when we were young, and our spouses' nieces were babies. We look up to the youngsters, and we aim to feel young. We reach such dream by usage of nanotechnology (sometimes it is not from a genuine source). Meanwhile, societies in general Harmonizes our hearts and jokes with our transsexualities to improve business. There is no prejudice to men and women marrying younger people. The whole situation occurs when the youngster is used by means of promoting the other wives and husbands only because they are still young and fresh, and get none.
