Social Presence and Physiological Health

Beyond diets, miracle remedies and “scientific progress,” the key to longevity lies in the depth of our connection to community.

Lessons from the “Blue Zones”

When we question health, we also question longevity, and we always look toward those few exceptional territories that demographers have dubbed the “Blue Zones”: the island of Okinawa in Japan, the province of Nuoro in Sardinia, the Nicoya Peninsula in Costa Rica, or the island of Ikaria in Greece. In these places, the proportion of healthy centenarians and nonagenarians defies all statistics. Yet, when searching for the common denominator among these populations, we don’t discover a secret diet or a particular gene, but above all a social structure where each individual maintains their place and their reason for being until their last breath.

In these communities, old age is not synonymous with withdrawal or isolation. On the contrary, elders are often pillars, transmitters of know-how, memory, and wisdom. They are not set aside, but remain at the center of family and community life, consulted and respected, quite simply, without the hierarchical mythology we are accustomed to or that cinema might portray. This constant intergenerational integration seems to me to be the first key. Presence in the world is not an option that one loses with age, but an inherent condition of existence, a thread that is never broken.

Therefore, each person’s contribution is not measured by their economic productivity, but by their simple participatory presence. An elderly person who tends their garden, who tells stories to the young, or who participates in village festivals contributes to the vitality of the social body. Similarly, a person with a disability, regardless of age, naturally finds their function within the measure of their possibilities. As psychiatrist Viktor Frankl explored, having a “why” to live, a meaning to one’s existence, allows one to overcome almost any “how.” In the Blue Zones, the community provides this “why” to each person, from birth to death.

Social utility, a fundamental need more than a pastime

Thus, active social presence is not a simple pleasant pastime, a “hobby” to occupy one’s old age. It constitutes a vital necessity, a true existential backbone, personal and collective, which also finds its physiological dimension. Being useful (and not just “feeling useful”), knowing that our existence has a positive impact on our surroundings, even at our level, without hierarchization, anchors the individual in life and gives the organism profound reasons to continue not letting its capacities wither. This is the exact opposite of the feeling of obsolescence and uselessness that gnaws at so many of our contemporaries in wealthy societies, and which constitutes, in my view, a major factor of morbidity.

Of course, one could object that such a vision, pushed to its extreme, would signal the end of the concept of retirement, this social achievement so dearly won in our unequal industrial societies. But I think this is wrongly framing the problem. My point is not to advocate endless work for the benefit of “bosses,” but to rethink retirement not as a social withdrawal, but as a transformation of our mode of contribution. It’s about moving from a utility dictated by economics and wage labor to a chosen utility, turned toward family, local community, transmission, and above all oneself. This requires recognition of one’s own value as a person within the community, which cultural rights are one of the tools for refounding. Sociologist Marcel Mauss, in his Essay on the Gift. Form and Reason of Exchange in Archaic Societies (1925), showed that human societies are structured around exchange and reciprocity, well beyond simple market transaction, regardless of age.

According to Mauss, the gift is never free: it is inscribed in a system of triple obligation: give, receive, return. This sequence structures social relations and constitutes a true social contract based on reciprocity. He demonstrates that, in many so-called archaic societies, each present offered engages the recipient to return a counter-gift, according to often tacit social codes. He questions: “what force is there in the thing one gives that makes the recipient return it?” He explores notably the Polynesian notion of “hau,” the “spirit of the thing,” which makes the given good remain linked to the giver, symbolically obliging the recipient to restore it in another form.

The gift for Mauss is a total social fact: it involves economic dimensions, but also religious, legal, political and moral ones, and I would add physiological. It allows the creation and perpetuation of social bonds, alliance and peace, much more than a simple market exchange. Mauss thus opposes the idea that economics is reduced to interest calculation; he shows that in giving, it’s about “having to be” and not “having to have.” And I also add: “giving to be in good health.”

Each person’s contribution is the antidote to the “financialization” of existence. In the Western world, an individual’s value is too often indexed to their productive or economic “performance,” starting from school. “Inactivity,” in the productivist sense of the term, is perceived as a cost, old age as a burden. The examples of Blue Zones teach us another path: one where a person’s value is intrinsic and where their activity, whatever it may be, has a purpose that is not monetary but relational. It is this liberation from pressure for profitability that generates profound serenity, conducive to health, personal and social.

The complementary pillars: frugality and serenity

This social presence, however central it may be, is accompanied by two other fundamental pillars that can be observed in these same zones:

• The first pillar is a form of alimentary frugality. Far from the diets of abundance and hyper-consumption that characterize the West, the inhabitants of these regions eat simply and moderately. They often practice, without even naming it, a slight caloric restriction, stopping eating before being totally satisfied, as the Confucian principle of hara hachi bu in Okinawa requires. This sobriety seems to me less a constraint than a logical consequence of a way of life where sources of satisfaction do not reside in material consumption, including through food ingestion.
• The second pillar is a notable absence of chronic stress. Activity is constant, but it is not experienced in the mode of urgency, competition, or performance anxiety. Life rhythms are more organic, dictated by seasons, natural cycles, and community needs rather than by the imperatives of an “external market.” This peace of mind, this capacity to live in the present moment without constant fear of tomorrow, has direct and measurable physiological effects, notably on reducing inflammatory states and hormonal regulation.

Ultimately, these three criteria, social presence, frugality and serenity, are not separate elements, but facets of the same art of living, a major key to physiological health. They nourish and reinforce each other in a virtuous circle. Strong social bonds soothe existential anxieties, which reduces the need to compensate through food or consumption. Frugality keeps the body and mind alert, capable of participating fully in community life. Serenity, finally, is the reward of a life perceived as just, coherent, and full of meaning.

All this is almost common sense. Why don’t we put it into practice more? It’s disarmingly simple. The elixir of youth is not for sale. It cannot be bought in pharmacies or supermarkets. It is woven, day after day, in the quality of the relationships we maintain with one another. If these simple principles were understood, valued, and especially shared with elderly people, they could radically transform the physical and mental health of our nations. The intergenerational is one of the keys to everyone’s health. And it is real, tangible and embodied social presence that changes everything. The true health of a State is measured, in my view, by the richness of the bonds that unite its citizens.
