I’ve noticed this doing the rounds within the skeptic echo-chamber … and well … its my turn, so here is Ben Goldacre (author of the Bad Science blog and also, least you wonder, for his day job he works full time as a doctor, so he knowns what he is talking about) … enjoy.
If curious as to why Ben was talking so fast … two reasons … he had lots to say, and he was being squeezed for time in a very packed program (they also had others such as Richard Dawkins and Brian Cox). I remember it well even now and loved every moment, as did my son who was also with me.
