From the NYTimes, The Island Where People Forget to Die. The article profiles the Greek island of Ikaria, where people routinely live in good health into their 90's.
The usual suspects of diet (olive oil, veggies, wine) and exercise (constant walking up and down hills) are mentioned, but the one that interests me is the low stress level. The Ikarians get plenty of sleep and have strong social networks. Nobody is rich but everyone has enough.
The contrast couldn't be much plainer to our own society. We have reached toxic levels of stress, and increasingly, we download our stress onto our children. School is one of the biggest stressors of all.
