It was great to see Sir David Attenborough on our screens once again last night. This time, he was telling us all about flightless birds in those homely, paternal tones of his. What amazes me is, he started presenting nature programmes before my parents were born, yet he still makes some of the most interesting stuff on tv. That’s why I’ll always make an effort to tune into his programmes.

I cannot help but wonder, though, how many more of his programmes we’ll see. It’s only a matter of time before the inevitable happens, yet David Attenborough’s nature documentaries have been such a constant in British cultural life for so long that it’s hard to imagine there being no more. For now, though, I think we’ll see plenty yet; and if they’re all as fascinating as the one last night I can’t wait.
