He's been in broadcasting for over 65 years and is regarded by his friends as a 93-year old trapped in a teenagers body. He's the only presenter to win a BAFTA for shows in black and white, colour, HD, 3D and 4K. This episode is devoted to the man who taught us all about the natural world and how we need to take more care of this fragile blue marble that we find ourselves on.

In this extended special edition, I look behind the scenes at what makes him a great presenter and what he thinks are the secrets to his success.
