Who does not want to stay forever young? Some people are blessed with a healthy body even in old age, others seem older than they really are. What is the secret behind that and is there a "fountain of youth"?
Aging - Our Enemy
We
have all experienced a feeling of panic and unease at some point when
thinking about our age. It usually first hits us as we approach 30, but
also probably returns when we retire. Reasons for this may lie in the
expectations we have for ourselves at the age of, let’s say, 18, when
looking into our future. We expect to look at an extensive summary of
our huge achievements, a clear purpose we served and a (mostly) fully
functional body and mind. But finding us far from this ideal position
can have disillusioning effects. So how can we learn to live the right
way from people who have already gone far?Old People crossing by Schnaars via Flickr |
Mapping the Blue Zones
Three
examples of Blue Zones are the Japanese island of Okinawa, parts of the
Italian island of Sardinia and Loma Linda in California, USA, each of
which independently developed their own ways of life.
Okinawans
follow strongly Confucius’s theories, which are ‘moais’: keep lifelong
friends (which also serve as close social support groups), ‘hara hachi
bu’ (eat until you are 80% full) and ‘ikigai’ (find a purpose for which
you wake up every morning). The religious group of Adventists in Loma Linda integrated their healthy habits to their belief system, by eating lots of nuts and beans high in mono- and polysaturated fats, fibers and various vitamins which are believed to contribute to health [3]. It is not known whether nuts contain something that extends life or whether their consumption just indicates a healthy lifestyle in general. They also drink plenty of water, exercise regularly and value their family relationships.
Now, reading this, one might get the idea of how to live the ‘right’ way in order to live a long and healthy life. What do the Blue Zone populations have in common? And what is so different compared to our ways of life?
Make the Life Years Count
Dan Buettner and his team summarized the common components of Blue Zones into 4 main points [4]: (1) All cultures move naturally and constantly using every single occasion. In our society the idea of exercise mostly means to work out for only 30-60 minutes every two or three days, whereas we forget our urge for exercise when we have to decide whether to take the stairs or escalator.
(2) The Blue Zones know how to live with the right outlook to life. Each of these cultures take time to relax by praying or caring for ancestors. When we are in a hurry and stressed out, our bodies trigger inflammatory responses that are associated with all kinds of disorders, from Alzheimer’s to cardiovascular disease. Slowing down for a few moments may turn these responses to anti-inflammatory responses.
(3) There is no longevity diet, instead these people drink a little bit of red wine, they tend to eat plant-based diets and have strategies that prevent overeating. Despite the increasing awareness of healthy nutrition, the vast majority of the western population is careless about what and how they eat.
(4) The foundation of all of this is how Blue Zone populations connect. They put their families first, take care of their children and aging parents and belong to a faith-based community. But the most important point is they belong to the right tribe, either by being born in it or by pro-actively surrounding themselves by the right people. Both healthy and unhealthy lifestyles of our loved ones, such as our friends, will probably have a measureable impact on our behavior over time.
When it comes to longevity there is no short-term treatment or miracle pill. But when you think about it, choosing the right friends is probably the most significant long-term action we could take to “add more years to our lives and more life to our years” [5].
