Nothing New Under the Sun

I find it interesting that recent trends in American society are really re-discoveries of ancient truth. At times it even seems ironic that certain movements are touted as a "new" idea, it makes me wonder if we in America have a short-sighted view of human history? Some of the many new-old trends in American society are home birthing and midwifery, co-sleeping, organic gardening, slow foods, whole foods, buying local, intentional communities, homeopathy and natural medicines, etc. I find it interesting that we have to rediscover such ancient truths, it begs the question of why we moved away from these in the first place? It seems to me that in most cases we moved away from what is normal and healthy due to expediency, hubris, or a combination of the two.

What new-old trends have you observed in society?
