Research shows that lifestyle factors have a significant impact on how long we live. While some centenarians, like Susannah Mushatt Jones and Juan Vicente Perez, have credited unhealthy habits like daily alcohol consumption or eating processed foods for their longevity, experts suggest these habits are not reliable for everyone.
They emphasize that while some individuals may live long lives despite their unhealthy behaviors, others who adopt the same habits may not be so lucky. Experts at Anglia Ruskin University, argue that these individuals are often the exception, and not the rule. Cortnage suggests that the reason there aren't more centenarians is due to the many others who smoked or drank excessively and did not live to 100.
The concept of "survivorship bias" is important here—people tend to focus on those who have lived long lives and believe their lifestyle choices are the key to longevity. However, Richard Faragher, professor of biogerontology at the University of Brighton, warns against taking health advice from centenarians who lived with unhealthy habits. Faragher explains that luck and genetics play a significant role in whether someone lives to 100, and these are factors beyond our control. Consequently, he argues that the advice from these individuals might not be as helpful as it seems.
In contrast, other experts highlight that making positive lifestyle changes can indeed help increase life expectancy. One of the most important factors for longevity is staying active, both physically and mentally. They also points to the concept of "Ikigai," a Japanese term meaning having a sense of purpose in life.
According to him, retirement and doing nothing afterward can be detrimental to health, while maintaining a sense of purpose contributes to longevity. Additionally, eating well is essential, with the Mediterranean diet being particularly beneficial. This diet, rich in vegetables, fish, whole grains, and olive oil, is associated with a longer, healthier life when paired with a balanced lifestyle.
Although many focus on the idea of living longer, experts stress that longevity alone isn’t the goal. Experts emphasize that it’s not just about adding years to life but about ensuring a healthy life expectancy, meaning people should aim to live as functionally as possible throughout their lives.
The research highlights that even if someone lives to an old age, they might spend many years in poor health, which is undesirable. The idea of living well, not just for longevity, is key to enjoying a fuller life.
