Blue Zones are five regions where people live measurably longer: Okinawa (Japan), Sardinia (Italy), Nicoya (Costa Rica), Ikaria (Greece), and Loma Linda (California). None of their secrets involve supplements or biohacking.

The Five Blue Zones

1. Okinawa, Japan — Highest concentration of female centenarians. They practice "hara hachi bu" — eating until 80% full.

2. Sardinia, Italy — Highest concentration of male centenarians. Shepherds walk 5+ miles daily.

3. Nicoya Peninsula, Costa Rica — Half the rate of heart disease of Americans.

4. Ikaria, Greece — Nearly 1 in 3 residents lives past 90. Almost no dementia.

5. Loma Linda, California — Seventh-Day Adventists who live 10 years longer than average Americans.

The Power 9

Blue Zone populations share nine lifestyle factors:

1. Move naturally — Walk, garden, do physical labor daily.
2. Purpose — Having a sense of purpose adds up to 7 years of life expectancy.
3. Downshift — Routines for shedding stress.
4. 80% Rule — Stop eating when 80% full.
5. Plant slant — Beans are the cornerstone of most centenarian diets.
6. Wine @ 5 — Moderate drinkers outlive non-drinkers.
7. Belong — All 263 centenarians studied belonged to a faith community.
8. Loved ones first — Family comes first.
9. Right tribe — Social circles that support healthy behaviors.
