Lessons from the World’s Oldest Person and Modern Science
By Mohan Manthiry, Editor-in-Chief, InfoMed (Malaysia).
Longevity has captivated human curiosity for centuries, with stories of ancient sages and modern supercentenarians inspiring us to wonder: what does it truly take to live a long and healthy life? The recent passing of Maria Branyas Morera, the world’s oldest person at 117, reignited this conversation, as scientists delved into her biology to uncover the secrets behind her extraordinary lifespan. Their findings, while focused on one remarkable individual, offer a compelling glimpse into the multifaceted nature of healthy ageing and the potential pathways toward a longer, more vibrant life.
The Individual Story: Maria Branyas Morera’s Remarkable Journey
Maria Branyas Morera’s life is a testament to resilience, adaptability, and the complexity of ageing. Born in 1907, she lived through two world wars, the Spanish Civil War, and multiple pandemics, yet maintained her health and lucidity well into her final years. Researchers seized the opportunity to study her genome and biological markers, hoping her longevity might illuminate universal truths about ageing. However, as Dr. Claire Steves, a leading geriatrician, noted, drawing broad conclusions from a single case requires caution. The ageing process is profoundly individual, shaped by genetics, lifestyle, environment, and sheer chance.
“When you’re only looking at one person, you can’t be sure whether or not what you’re seeing is because of just a fluke, you can’t be sure that the relationship is really clear,” Steves explained. However, focusing on individuals who defy the expected boundaries of human lifespan can still spark valuable insights, especially when their biological data is examined in detail.
Is Ill-Health in Old Age Inevitable?
One of the most striking results from the study of Branyas Morera was the assertion that “extremely advanced age and poor health are not intrinsically linked.” This challenges a pervasive belief that growing older inevitably means declining health and frailty. Instead, the research revealed that ill-health in advanced age arises from specific biological mechanisms—many of which are potentially modifiable. This perspective shifts the focus from mere lifespan to ‘healthspan’, the number of years spent in good health, free from chronic disease and disability.
“Ill-health in age is not inevitable. It comes about because of biological mechanisms … it’s something we can change,” said Steves. The implication is clear: by understanding and targeting these mechanisms, we may not all live to 117, but we can certainly strive to ‘squash’ the period of illness and suffering to as brief a window as possible.
The Genetic and Biological Puzzle
The key to longevity lies not in a single genetic quirk or lifestyle habit, but in a complex interplay of factors. By examining Branyas Morera’s genome, scientists identified several genes and proteins associated with healthy ageing. These discoveries open the door to the development of targeted therapies—drugs and interventions designed to preserve cellular function, reduce inflammation, and optimise the body’s resilience against disease.
Dr. Manel Esteller, who led the genetic analysis, hopes these findings will guide the next generation of anti-ageing research. “Our aim should not necessarily be to all live to 117,” Steves added. “What we want to do is to try and squash the time when we’re unwell and suffering to as small a time as possible. And that’s what this lady seems to have done, as well as living to a long time.” The goal, then, shifts from chasing immortality to enhancing quality of life in our later years.
Female Longevity: Unique Insights
Women, on average, tend to live longer than men—a phenomenon observed across cultures and eras. Dr. Vonda Wright, a longevity expert, emphasises several key factors relevant to female longevity that apply to all. These include maintaining strong social connections, prioritising mental health, and engaging in regular physical activity. Nutrition plays a pivotal role, with diets rich in fruits, vegetables, whole grains, and healthy fats supporting cellular repair and reducing inflammation.
Hormonal factors also contribute, with oestrogen offering some protection against heart disease and osteoporosis. However, the transition through menopause introduces new challenges, making tailored healthcare and lifestyle adjustments crucial for women seeking to extend their healthspan.
Pathways to Healthy Ageing: Lessons for Everyone
- Stay Physically Active: Regular movement—whether it’s walking along the footpath, swimming at the local pool, or joining a community sport—boosts cardiovascular health, maintains muscle mass, and supports mental wellbeing.
- Cultivate Social Bonds: Loneliness is a significant risk factor for ill-health in later years. Staying connected with mates, family, and neighbours helps combat isolation and fosters emotional resilience.
- Eat for Longevity: A balanced diet, high in plant-based foods and low in processed sugars and saturated fats, protects against chronic illnesses and supports a healthy gut microbiome.
- Prioritise Mental Health: Mindfulness, meditation, and regular engagement in meaningful activities can stave off depression and cognitive decline.
- Adapt and Learn: Lifelong learning, whether through reading, volunteering, or picking up new skills, keeps the brain sharp and helps maintain a sense of purpose.
The Future of Longevity Research
While the study of supercentenarians like Maria Branyas Morera provides tantalising clues, the science of ageing is still in its infancy. Future research will need to replicate these findings across larger, diverse populations to unravel the true secrets of healthy longevity. The hope is that by identifying the genes and pathways involved, researchers can guide the development of drugs and lifestyle interventions that target these elements directly.
Ultimately, the pursuit of longevity is not simply about extending life, but about enriching it—ensuring that our later years are spent with vitality, independence, and joy. As we learn from the lives of extraordinary individuals and the discoveries of modern science, each of us can take practical steps towards a longer, healthier future. So, whether you’re taking a stroll to the local servo or enjoying a cuppa with friends, remember: the keys to longevity might be closer—and simpler—than you think.
