The Sinusoidal Life Cycle

I guess I found an answer to this question of age. A lot has been written on the matter, I know. But I observed that people start aging when they start acting like adults, at any age, it does not matter, and then they stop aging, or rather start de-aging, when they start speaking and acting their mind, stupidly most of the time, like babies. Babies don't really think about the implications of their actions or words. They just say the first thing that comes to their minds and so do many people at an "old" age. So, people can age, then de-age, then age again, then de-age, and so on. Others keep on aging until they are wise enough to realize that they need to de-age. That's the real life cycle. In fiction, the distorted life cycle gets more interesting. In Fitzgerald's "The curious case of benjamin button", the reverse life cycle is a bit annoying but the best said was by Georges Costanza in Seinfeld: "The most unfair thing about life is the way it ends. I mean, life is tough. It takes up a lot of your time. What do you get at the end of it? A death. What’s that, a bonus?!? I think the life cycle is all backwards. You should die first, get it out of the way. Then you go live in an old age home. You get kicked out when you’re too young, go collect all your super, then, when you start work, you get a gold watch on your first day. You work forty years until you’re young enough to enjoy your retirement. You drink alcohol, you party, and you get ready for High School. You go to primary school, you become a kid, you play, you have no responsibilities, you become a little baby, you go back into the womb, you spend your last 9 months floating with luxuries like central heating, spa, room service on tap, then you finish off as an orgasm!"
