Living to 100 remains exceptionally rare, but a handful of celebrities who have reached that milestone credit surprisingly straightforward habits. David Attenborough celebrated his 100th birthday on May 8, becoming the oldest Daytime Emmy winner in 2025 at age 99. The naturalist has said that connecting with nature helped his health.
According to scientists who study aging, genetics play a role in longevity, but lifestyle factors — including diet, exercise, stress management, and social connections — matter more. The celebrity centenarians highlighted by Business Insider kept their routines simple rather than adopting extreme wellness regimens. George Burns took brisk walks and avoided stress, while Jimmy Carter credited marrying "the best spouse."
These examples underscore a growing body of research suggesting that modest, consistent habits can extend lifespan. Social engagement and mental stimulation appear particularly valuable. Kirk Douglas and other stars in the list also emphasized maintaining purpose and staying active into old age.
Critics might argue that celebrity longevity advice often lacks scientific rigor and may not apply to average individuals with different socioeconomic circumstances. The sample size of 11 is small, and genetic luck still likely plays an unmeasured part. Nonetheless, the common threads of activity and connection offer accessible takeaways for anyone seeking a longer life.
