Sir David Attenborough: I'm just having a ball on TV
Sir David Attenborough has been the voice of the BBC's wildlife TV shows for 60 years, but even at 87 years old he says we haven't seen the last of him.
Newsbeat spoke to the veteran broadcaster about the future, his health and his latest projects.
In June this year David Attenborough had to cancel a trip to Australia to have a pacemaker fitted.
Since then he has flown to China to speak about feathered dinosaurs and is currently working on nine programmes.
His latest series follows backboned animals through 500 million years of evolution from dinosaurs to humans. He described it as "taking some time".
Despite having a pace maker fitted earlier this year Sir David says "it's not a big deal really".
He had what he described as "a giddy moment", but when asked if he has had one since he replied, "in fact I just had a check-up and it's [pacemaker] hardly been used, possibly not switched on at all".
He laughed when asked about his replacement, with two programmes in the coming weeks and another nine on the go as well.
Speaking at UKTV's 2013-14 Showcase, Sir David Attenborough said he was confident he had far more broadcasting left in him yet.
"I'm just having a ball," he said.
He added that he had always wanted to go to China and his new series allowed him to do that but he didn't have to go to many of the locations shown in the programmes.
"Sometimes it's just not necessary to send a presenter to be in shot, but China, I had to talk to the scientist who made the discovery."
That discovery is about some dinosaurs being covered in feathers.
Rise Of Animals: Triumph Of The Vertebrates begins on Friday 20 September at 9pm.
