One of the goals of most mature people is to pass along our accumulated wisdom to the next generation or (and more likely) to a generation after that. Altruism surely enters into this impulse and a genuine concern for the welfare of children we either know or are related to. The biggest motivation is the desire to obtain reassurance that our accumulated wisdom is, in actual reality, of greater value than merely half a dozen decades of speculating.
Here is an example which helps to order and organize an aspect of life which a single individual's personal experience may be insufficient to illuminate: In the context of dreaming about being actively, physically threatened by agents of an evil power such as (for example) a Mafia-style criminal organization, the Immigration and Customs Enforcement agency, an invading foreign army, or an opposing team in a serious game of Capture the Flag, and if in that context you are going to throw yourself out of bed onto the floor, then you should take care to roll your body so as to land on your butt rather than your elbow. (The elbow has relevantly less padding to absorb the impact.)
A member of one of the younger generations may be dismissive of this advice. "I do not dream about criminals threatening me," he may scoff. But you might once you have enough experience to know such criminal behavior is pervasive. "I am not going to throw myself out of bed," she may insist. But would you throw your body behind a masonry wall in the face of an imminent even if imaginary threat? Most evasive and protective behaviors are actually in response to imaginary threats; just look at all of politics for examples.
Counting myself among the mature -- being well past half way to centenarian status I am therefore mature by status without need to prove maturity by merit -- I too am desirous of passing along the fruits of my experience and reflection. I have to wonder, though, whether the conclusions I have reached are are the fruits or merely the flowers of this process. In actual reality isn't the example of a reflective and self-aware manner of life of more significance than the specific and often tentative conclusions which are reached along the way?
Flowering rationality is meant to pass away replaced by maturing fruits within which the germ of continued reasoning is held.
