I have several. I suppose the 90's decade for me before tech took over everywhere. But just enough tech to make it exciting. I was in my late teens and early twenties, when I was still naive and innocent enough to make sweeping excuses/generalizations for many things. Music was still good across the board mostly, except perhaps country music that really started to morph into something I would not personally call country. Yet there were still a few good country artist left. Lots of interesting music sprung up in that decade.
If I were to pick a time period, I would probably say the late 1800s. Steam engine Locomotives were still going strong and that would have been exciting. Horse and buggy was still a main mode of transportation for the masses.I love horses and I love wagons and carriages. Cars were starting to be invented and I imagine that would have been exciting. Also the life style of living off the land was normal and no one would have looked at me any different if I said I had a cabin in the mountains. Since there were not radios there would be a lot of quite times to listen to nature. Also I can imagine the thrill of going to see a live Concerto and those sounds blissfully playing in my ears days and days after. Clothing and tools would be made of stronger quality. Also the satisfaction of using hand tools, making your own home. Growing your own garden, having chickens,ect without someone thinking a thing of it. It would have be the norm. Books would have been amazing to read. Things like the writings of Jules Verne would have been simply mind blowing.
Also I'd probably be pretty okay with living as an indigenous person in the Andes mountains, now or hundreds of years ago. Half naked with some bamboo wrapped around... umm , urrr the lower regions of the body.
I would love to be able to see first hand how it was to live 5000 years ago, knowing me I could see myself as a stoic of sorts that was forced to drink poison like Socrates. lol.
There are still places on this planet that are generations behind, so if I should live long enough perhaps I will be able to put myself in one of those places. Like 'rural' Romania, Mongolia, Argentina, Switzerland, Chili, and more.
Thanks Minimus for posting this question. It took my mind to fun places.
