That Sir David Attenborough is still making landmark nature documentaries at the age of 91 is already a staggering achievement, but the broadcaster has revealed he fully intends on working past his 100th birthday, which would mean reaching a milestone of 75 years in television.
Ahead of Blue Planet II, which launches on BBC One on Sunday, Sir David said (via The Sun): "I see no reason whatsoever why I can’t live past 100.
"Earth has enough wonders to make more than three Planet Earth series."
The naturalist recently said that he is "coming to terms" with the fact that he is "running into problems" with his memory, but still shudders at the word retirement.
"You never tire of the natural world," he told us. "Putting your feet up is all very well, but it’s very boring, isn’t it?"
Beyond the ocean-based Planet Earth II, Sir David also has films prepared on ants, extinct sea-dragons and elephants.
