Do you believe this bloke Ninesy? Look him up. The only thing I’ll say is that he was a GP, but resigned from the NHS in 1981 and has been long removed from the list of practicing doctors by the GMC.
I listened to it all the way through and, regardless of his background, didn't think he claimed as fact anything that wasn't factual. There was the suggestion of some plot against the older members of the population at the end, of course, but not proffered as anything other than a question.
