Must be said, the last few podcasts of this have been excellent. Especially the one on 'What is Race?' Some fascinating stuff, for instance, how far back in time do you have to go before everyone who is currently alive in Europe can be traced back to a person who was alive then? Answer in the podcast 
Also the one last week on 'The Maths of Love and Sex' was really good as was the one 'What is Reality'. Where they said something like the chances are what we perceive as reality is actually half a second in the past. Or something like that, I didn't quite understand. Well worth a listen to nourish your brain whilst you are out walking the dog.
