life expectancy

In most of the developed world, life expectancy has steadily increased over the past couple of centuries. In America, however, it is sliding backward. According to data from the Centers for Disease Control and Prevention’s National Center for Health Statistics, the average American life expectancy was 78.6 years in 2017, which was down slightly from the previous year (Murphy et al. 2018). Arguably, modern lifestyles—including sedentary behavior and poor eating habits—are a breeding ground for chronic illness, making it harder for people to live long and prosper.

Yet, there are regions around the globe where pockets of people do appear to enjoy a longer, healthier life expectancy. In these so-called Blue Zones, residents statistically live the longest and produce nonagenarians (ages 90–99) and centenarians (100 years old and above) at seemingly extraordinary rates. The specific areas are Okinawa (Japan), Sardinia (Italy), Nicoya (Costa Rica), Ikaria (Greece) and the Seventh-day Adventist religious community in Loma Linda, California (USA) (Willcox et al. 2006; Poulain et al. 2004; Buettner 2008).
