Thank you for downloading the More or Less podcast from the BBC.

You can find out more about our programme on our website,

bbc.co.uk slash radio4.

But before you do that, here's Tim Hart.

Oh.

Hello, I'm Graham Seed, the new presenter of More or Less.

You may know me from the archers,

but my real love is mathematics and the numbers that surround us every day.

This week we ask, just how big is a hectare?

Why do we count sheep rather than say cows?

Is it possible to cull an exponentially growing population of badges single-handed?

And we'll solve that age-old conundrum.

How many men did go to know the meadow?

But first, hey, what's going on?

Tim, I thought you were dead.

At the end of the last series, you fell from the roof of white city,

falling a total of 20 metres, evidenced by a rather weedy scream,

time precisely at two seconds, which is why I applied for the job of presenter of More or Less.

Well, it was a big fall, but I got better.

I see.

I wish I had.

So does everyone else, Graham, but they can direct their complaints to the drama department.
