Given a Pacemaker, Knee Surgery and Memory Loss – But He Still Fights for the Planet

Sir David Attenborough may be known for his calm voice and unwavering presence on screen, but behind the scenes, the beloved broadcaster has faced a number of serious health battles.

Now aged 99, the national treasure recently made headlines with a heartfelt admission in his latest Disney+ documentary Ocean, stating he is “nearing the end of his life.” It was a sobering moment from a man who has spent nearly a century observing and protecting the natural world.

But this powerful reflection didn’t come without years of personal struggle.

Back in 2013, Sir David underwent emergency heart surgery to fit a pacemaker. Doctors deemed the procedure urgent, and it forced him to cancel a sold-out speaking tour in Australia. “You can’t take a long-haul flight after something like that,” his spokesperson explained.

Just two years later, at age 87, he underwent what he called a “nasty” knee operation, which left him briefly immobile. “They didn’t want to do both knees at once,” he recalled. “I would’ve preferred that, but it’s too much anaesthetic at my age.” Thankfully, the surgery allowed him to continue walking and filming for hours at a time.

And in 2016, Sir David openly acknowledged signs of memory loss, saying it had started to affect his ability to write. “I just couldn’t remember the name of a flower while filming,” he said, referencing a trip to the Jura Mountains. “It wasn’t until much later I remembered: oil seed rape.”

Despite these challenges, Sir David never stopped working. With Planet Earth III and Ocean, he’s continued to inform and inspire, even as his body reminds him of time’s passing.

In his most recent statement, he reflects not just on his own mortality, but on the future of the planet. “As I approach the end of my life, I now understand the most important place on Earth is not land – but sea.”

It’s a message of urgency, but also hope – from a man who has given everything for the planet, and who is still fighting to protect it.
