>Do you think life would be better if we had start doing things the it ways years ago.
Life is what you make of it. Of course, you should completely define what you mean by "better".
>How long do you think it could last?
About as long as it takes to realize what kind of conveniences were lost. When people start dying of diseases that are trivial to cure now, or suddenly the workloads and travel times quadruple (or become impractical), that's about how long people will accept the "simple" lifestyle.
>would you embrace such a simple lifestyle??
My life revolves around technology, so no. I think that even those who say that they would embrace it probably aren't considering all of the variables either. What you suggest doesn't sound like cutting back on one or two complexities, more like a whole scale removal of technology. Since technology permeates pretty much everything in our lives, it's easy to misunderstand exactly what you'll be giving up.
>You think you could adjust???
I have little doubt that I could.
