Human longevity: Secrets to a very long life

Living a long, healthy life is a dream shared by many, but only a few manage to break past the average life expectancy. From ancient herbal remedies to modern scientific advances, the pursuit of longevity has fascinated both researchers and ordinary people. What makes some individuals live far beyond 100 years? Genetics plays a part, but they are far from the whole story. Daily habits, mindset, diet, and even social life seem to hold surprising power over how long—and how well—we live.

While genetics might set the stage, it’s the lifestyle choices that truly influence the outcome. Factors such as what we eat, how we manage stress, and even how often we laugh can be just as important as medical care. In this article, we’ll explore the real-world secrets to longevity that are grounded in everyday living and supported by science.

Daily habits of the oldest man alive

In the case of the world’s supercentenarians, their stories give powerful insight into the practical choices that may extend a person’s life. One example is the oldest man alive, whose daily routine surprises many. Unlike common assumptions that living longer requires strict routines or expensive supplements, his habits are remarkably simple. He wakes up early, avoids processed food, and spends a lot of time outdoors. He also maintains strong social bonds—having conversations daily with friends and family, which researchers link to improved mental health and lower chances of chronic illness.

Physical activity is also key. He doesn’t run marathons or lift heavy weights. Instead, his daily routine includes walking, gardening, and other low-intensity movements. This consistent, moderate activity seems to be enough to keep his body and mind sharp, even past the age of 110. His story echoes findings from “Blue Zones,” regions in the world where people regularly live past 100. These communities share common habits: eating whole foods, staying active naturally, and maintaining close relationships.

Nutrition and the role of plant-based eating

One major element linked to longevity is diet. People who live the longest tend to eat more plants than meat. Meals rich in vegetables, beans, whole grains, nuts, and olive oil are a common theme in long-living cultures. Red meat is often eaten sparingly, if at all. Fermented foods like yogurt, kimchi, and miso also support gut health and may help reduce inflammation, a common issue as people age.

Another vital factor is eating patterns. Many elders who live exceptionally long lives follow what’s known as “hara hachi bu,” a Japanese principle of eating until you’re only 80% full. This prevents overeating and supports a healthy metabolism. In contrast, people who frequently overconsume—even healthy food—may face increased risk of disease later in life.

Mental health, purpose, and community ties

Mental wellness is just as important as physical health when it comes to living longer. Feeling connected, useful, and mentally active can significantly reduce the risk of depression and cognitive decline. People with a clear sense of purpose tend to live longer and feel happier overall. In some cultures, there’s even a word for this—“ikigai” in Japan, meaning “a reason to live.”

Elders in tight-knit communities also enjoy lower stress levels and better access to help when needed. Social isolation, on the other hand, has been shown to increase mortality risk. Whether it’s through volunteering, mentoring younger generations, or staying involved in hobbies, meaningful connections appear to be a powerful ingredient in the recipe for long life.
