When I was ten I informed my Mother I wanted to live at the big county Library .
Now with the internet I'm good.
Ha, I loved this answer!
For myself, I think each time period had its checks and balances. For example the purer food and water of yesteryear meant less medical advances etc.
Given that, I would pick now with the following provisos
Eat pure food
Live close to nature
Those would be the checks (the easy part)
Challenge your body to the extreme
Challenge your mind and emotions to the extreme
Those would be the balances (the challenging part)
Avoiding constant temperature control by experiencing true cold and heat.
Not taking a pill for every symptom
Building your own home or if thats too ambitious, a chicken coop!
Trimming the "fat" that dulls the senses such as social media, constant cell phone and internet. I guess I would also include most news outlets, and what passes for entertainment in USA (the only country Im familiar with).
Really as I think about it, NOW is the only time that would allow a person to pick, choose and customize a life based on all that has come before.
Confession: I am writing this while sitting in an air-conditioned home after eating a more than substantial lunch and while browsing the internet. Soft easy living much? I suspect so.
