'The van Tullekens are the pin-up doctors at the forefront of HIV research, medicine in war zones and the Ebola epidemic. They're so warm and likeable that they've made roughly 20 TV shows between them in the past ten years. Proving that smart is indeed the new sexy, both van Tullekens are highly qualified doctors researching and treating infectious diseases, while their shows tend to involve hair-raising, death-defying or body-hacking challenges - all carried off with inexhaustible good humour in the name of science. Indeed, at the age of 36, their bucket list is as short as Chris' stubble: to date they've trekked to the North Pole, shoved spikes through their tongues and even won a BAFTA.' Evening Standard
