We're off on our summer hols, so here's perhaps our favouritest interview wot we have dun. We had an amazing natter in 2018 with Vybarr Cregan-Reid - author, runner, academic and as you'll hear, proper good natterer. Yer Babble's back in September.

Vybarr is not only the most fabulously named babble guest we've had, but also the author of TWO incredible books about humans and our environment.

His new book - Primate Change: How the world we made is remaking us - uncovers the extraordinary tale of how our environment has changed our bodies, from our eyes and teeth down to our toes, while 2017's Footnotes: How running makes us human reconnects us to our bodies and the places in which we live.

We pick Vybarr's mega brain in a wide ranging chat, during which - as well as discovering how the treadmill killed Oscar Wilde - we learn that Dave is in fact no more than 25% Dave.

And poo transplants get a mention.
