Dr Michael Mosley is a man prepared to put his body through almost anything all in the name of science.
In a new BBC Documentary he infects himself with a load of gruesome parasites to see how they affect the human body.
Dr Mosley's experiments are not for the faint-hearted and certainly not to be tried at home.
Dr Mosley is a trained, qualified and experienced doctor who did these experiments under close supervision. Do not try anything like this yourselves.
