Sir David Attenborough celebrates his 100th birthday today, May 8, marking a century of passion for the natural world shaped by his early years in Leicester. The renowned British naturalist has narrated iconic natural history series for over 70 years, bringing wonders like those in Life on Earth, The Private Life of Plants, and The Blue Planet into homes and classrooms worldwide. At 100 years old, he remains active in broadcasting.
Key to Longevity: A Shift in Diet
Sir David credits much of his vitality to a simple change in eating habits. While not fully vegetarian, he has significantly reduced red meat intake, a move he links to his enduring health.
This adjustment dates back to at least 2017, when he shared: “I have certainly changed my diet. Not in a great sort of dramatic way. But I don’t think I’ve eaten red meat for months.” He continues to enjoy cheese and fish but describes himself as “much more vegetarian” than before.
Attributing Success to Pure Luck
The celebrated broadcaster and historian once pinpointed sheer luck as the main reason for his sharp mind and strong body. Ahead of his 90th birthday in 2016, Sir David stated that his well-being, compared to many peers facing age-related challenges, stems from “not Christian virtue, just luck.”
BBC Marks Milestone with Special Programming
The BBC honors this landmark with a week of dedicated content, featuring the new documentary Making Life on Earth: Attenborough’s Greatest Adventure. It provides an exclusive behind-the-scenes glimpse into his groundbreaking 1979 series Life on Earth.
