I think it's important to note that they're luxuries in the modern society we've built for ourselves in the West. Long, long ago, small communities without access to high-speed travel provided social support; no cars and little white-collar work means exercise was baked into life with much walking and manual labor; diet was mostly unprocessed food farmed nearby; and no screens or even electricity meant sleep well before midnight till dawn.

Of course, there were plenty of problems back then, too - I'm not saying it was an idyllic utopia. But in our modern life, it seems like we've just traded one set of problems for another.
