Is back-to-basics a fad? For some folks, I'd venture to say that the answer us a strong "yes". There are a lot of fad activities out there which draw people for a few months before they lose interest. When I was younger, square dancing was a fad activity where I lived. Everybody who was anybody in the neighborhood took part in a square dancing group. Eventually the interest died.
Exercise gyms were the in thing for awhile. Many of my friends and neighbors, plus all my employees, paid their year's gym membership, then lost interest after a month or two.
I'm plenty old enough to see dozens of food fads come and go. In fact, they've even more popular than gardening and homesteading.....if one uses a bookstore as the judge. Barnes & Noble actually devotes more wall space to fad diet books than to food growing books.....presently more than twice as much.
Yes, fads come and go. But I find it a sad commentary to see the basics of living to be a passing fad.
