My previous avatar was Thomas Young... a measure of the arrogance I enjoy in my inner self.
Something about an excellent liberal arts background builds in a thirst to know more about everything and anything. The structured learning of a semester or two of art, religion, astronomy, psychology, physics, chemistry, literature, languages, history and the 12 other disciplines that were part of the process... establishes a frame for building on any new interest. Even ROTC provided a base for understanding strategy and tactics.
The freedom of an uncomplicated retirement (especially in the later years, when the social whirl has past) allows for the most exciting part of discovery... not slowed by classroom or preplanned study courses. Go as far and as fast as the interest calls for... no tests, no "must knows", no waiting for others. Pick up and drop the study before boredom sets in. Nothing to prove to anyone else.
The single thing that has helped me most, in learning from the internet, is using the visual tool to standardize the different page layouts, type faces, type sizes, and eliminating the advertising distraction... is
Readability... which I use on all websites.
So, as to the afterlife... much, much on philosophy and the Weltanschauung.
Without the aforementioned "structure" the ability to move from interest to interest... today religion, then medicine, then technology and politics, economics, music... No standards, no tests, no challenges, interruptions or any roadblocks... because... because... there is only one person to satisfy.
Sometimes we become so inured to "following" as a part of education, that we miss the absolute joy of being a sponge to soak up the available.
For the very few times when a mental lull sets in for a few minutes, a quick visit here, is like a shot of adrenaline.

Then, of course, there's the matter of vanity... of knowing enough about the world to be comfortable in any area of interest. An example of this, is my recent part time fascination with farming. (We live in a rural area, where many of the most successful people my age... were farmers) I am developing some humility on the subject... much more than meets the eye. A bit of a blow to the ego, but temporary, as latest farming technolgy is leaping ahead of experience.
I have recounted here, my onetime dream of throwing a brick through the bank window, to be put in jail for a month or two... with time to read at heart's content. So yeah... lving a dream... past the point of responsibility and into the wonderful world of yestrday, today and tomorrow. Much more on my plate than Thomas Young ever had. He had to build knowledge from scratch, to grow from seed. I, (we) have only to stroll through the garden and pick and choose the fruits of what has been provided by those who have gone before.
Retirement and age... the best of all times. Philosophy guided by John Milton in his sonnet-- "On His Blindness".
