Not a paradise of mine (that I'm researchin'), but here's an utopia with past tech* I thought you might be interested: "Walden II" by Burrhus Skinner, conceive a "small-time" utopia-like fictional effort, inspired by science, without any "alternate history" (in the law-and-politics scale). Just sheer enterprising.As a genre of fiction, it's quite cool. It inspired quite a few hopeful real-life "utopian communities" as well. Some with stories that can be read online: of both failures and achievements. Some ongoing right now, and can be visited with the proper previous announcement and subsequent consent (people's homes, after all).If anyone reading this becomes interested in some planning, and would like someone akin to periodically talk to, no bets attached, I can be found online for message exchange._____________*current tech, when written. The passage of real-time and new techs are addressed on a fiction-continuation article, "News from nowhere, 1984" by the author.
Fellow humans, do forgive my newbieness, but I am surprised this following study has not been mentioned: - https://www.aging-us.com/article/202188/textI speak no chemics, so I might've lost something midway of the presentation. Yet, since I have celebrated the aforementioned article as my most cherished 2020 article, I've guessed the chance of it cherishing someone's day upward was worthy of the hereby mentioning. I shall read replies probably: in case I take time to do so, one may consider oneself thanked for the reply, in advance.
