It seems like most people who want the known choose recent history and most people who want unknown choose the future.
It'd be pretty impossible for me to give up the modern day forever (and the people I know and my knowledge and moral reasoning). But if approached as a 1 or 2-yr "study abroad" program, I think I'd jump at the chance.
It's not so much that modern technology constrains us as much as it is our mental mindest. Better technology has been a pursuit advantageous through most of human history. From the first person to throw a spear to the creation of vaccines. But we are set in a certain mental pattern of our times.
Not that past times have fewer mental blocks (and some difficult physical ones to boot). But different ones. To flex a new part of my brain would be a magnificent learning experience(and likely, my body, my couch potato-ness sobs).
For example, I rely a lot on written language in order to understand and analyze the world. What is it like where most people can't read or write? A world where it is not so important to "coin" a word or phrase for a new idea- it is important to show. Where a story, a history, a meaning isn't quoted/rehashed- it's experienced over every time.
A world where the mixing and blending of local culturse and religions is not (I recently read Herodotus's description of Egyptian culture during his time and his discussion on the travel of local Gods to new areas using different names is fascinating) as necessarily opposed- since perhaps without as many labels, they aren't as divided into "this" group or "that" group- allowing the degrees in between- the ambiguity of fewer words.
Plus, I'd like to see what it'd be like to live in a matriarchal society for once. To feel like the more powerful gender.
All supposing I'd survive this trip. And be able to assimilate in some way. Though if I died, I'd be dead and wouldn't care either way. And everyone has to die
somewhere.
