David Attenborough Turns 100, Longevity Explained by Genes, Habits and a Bit of Luck

Sir David Attenborough turns 100, and the piece reviews how longevity arises from a mix of luck, genetics, and healthy habits. While genetics set a baseline, studies including the New England Centenarian Study suggest a strong role for lifestyle and sense of purpose in aging well. Attenborough’s active lifestyle and ongoing work align with evidence that purpose and activity contribute to health, though figures like Maria Branyas show that exceptional longevity often results from a combination of genes, diet, social life, and environment. Population data indicate centenarians are becoming more common, but reaching 100 remains rare (~0.025%); there is no single formula for long life, only an interplay of biology and lifestyle.
