100 years of David Attenborough: 6 lessons on how to live a long life well

As one of Britain’s most beloved public figures, Sir David Attenborough carries with him an esteemed legacy:

• He has been knighted twice, once in 1985 and again in 2022.
• He holds 32 honorary degrees from universities around the UK.
• He has made more than 100 documentaries exploring life on Earth, inspiring millions of people across the globe.

Now, he has celebrated yet another lifetime achievement – reaching 100 years of age on 8 May 2026.

Inspired by his legacy, here are six lessons you can apply to your own life to help you live better for longer.

1. Live with passion and purpose

David Attenborough has dedicated himself to exploring the natural and biological wonders of Earth and sharing this beauty with the rest of the world.

He has never wanted to retire. In a 2010 interview with the Telegraph, he said, “I can’t imagine why I would want to: this is such fun. I can’t believe my luck that at my age there should be so many things to do.”

While you might hold a different perspective on retirement, his passion exemplifies the importance of finding purpose in later life.

Whether you decide to volunteer, take up a new hobby, or explore more of the world yourself, approaching later life with a clear ambition means you’re likely to remain fulfilled, no matter your age.

2. Spend more time in nature

Naturally, David Attenborough spends as much time as possible in nature and urges others to do the same, even if it’s just for 10 minutes a day.

Most people benefit from more exposure to nature. According to research from Aviva, 80% of those who spend time in nature reported that it boosted their happiness levels. 74% reported feeling less anxious and stressed after being in outdoor environments.

As you reach your later years, spending time in green spaces becomes even more important for your mental and physical wellbeing.

3. Challenge yourself

Despite being a century old, David Attenborough shows no sign of slowing down.

On top of the 100-plus documentaries he has narrated, his latest, Wild London, was released in January 2026.

Just as David Attenborough continues to challenge himself by releasing more documentaries each year, it’s also vital that you keep engaging in activities that challenge your brain.

In fact, according to Alzheimer’s Research UK, doing so helps you build “cognitive reserve”, which protects your brain against decline.

4. Eat well

In his 90s, David Attenborough decided to start cutting back on red meat, adopting a primarily vegetarian diet.

While this may have been for personal reasons, according to the NHS website, lowering your red and processed meat intake has been linked to a reduced risk of bowel cancer and high blood pressure.

Lowering your overall meat consumption can also have widespread benefits for the environment, reducing the presence of greenhouse gases from agricultural and land use, which is important for the future wellbeing of your children and grandchildren, as well as your own.

5. Keep your heart healthy by staying active

It’s no surprise that the more active you are in your later years, the longer your life expectancy will be.

While he’s never run a marathon, David Attenborough has always stayed physically healthy by keeping mobile. Today, this is mostly from regular walks around his hometown of Richmond.

According to the British Heart Foundation, regular exercise can reduce your risk of heart and circulatory disease by up to 35%.

To stay in shape, experts recommend around 150 minutes of moderate-intensity exercise, like brisk walking, jogging, or cycling, per week.

6. Maintain a busy social life

Though he’d likely prefer to spend most of his time alone in nature, David Attenborough maintains a very active social life, whether that’s through his work or through spending time with his children and grandchildren.

In fact, he spent part of his birthday surrounded by thousands of people at the Royal Albert Hall for his live special, David Attenborough’s 100 Years on Planet Earth.

Data from the International Longevity Centre shows that both the size of an individual’s social network and the frequency of contact are positively associated with high levels of wellbeing over time.

Additionally, those with a high degree of loneliness are twice as likely to develop Alzheimer’s disease as those with a low degree of loneliness.
