What do you mean by "old conventional way of living?"
People have the ability to choose how they wish to live. Anyone is free to give up any level of modern conveniences that they have in their life and consciously choose to live in a way that harkens back to some earlier time. Most people have panic attacks at the thought of not having the Internet and that technology is just a few decades old at most.
I would not enjoy giving up the level of modern health care that I have been raised with.
