Sir David Attenborough: I'm just having a ball
Sir David Attenborough has been the voice of the BBC's wildlife shows for 60 years, but even at 87 years old he says he's not finished yet.
The veteran broadcaster has been speaking about the future, his health and his latest projects.
In June Sir David 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 now working on nine programmes.
Sir David was speaking to Newsbeat reporter Tom Martienssen.
