Ok interesting. I was wondering because I am trying to get a fix on whether there might be a pattern over time on some of those issues. Some people really have no interest in the "physics" whatsoever. Now I myself am not at all a fan of the astro and quantum theories such as "string theory" and the like, but I do think that a certain amount of study of the "Workings of nature" in a general sense is helpful.
As for the latter question, i have moved toward splitting my time between city and countryside, and moving more toward the country as I grow older. So it's interesting to me that Diogenes Laertius specifically recorded that Epicurus said the wise man "will be fond of the country."
Also I apologize if you're stated this already in detail but what was it that spurred your interest in Epicurus?
All these are areas to look for clues on how things can be made better, I think.
