DOCUMENTARY: Infested: Living with Parasites (BBC Four, 9pm)
Thanks to the growing popularity of digital video recorders, it’s now easier than ever to watch TV shows at any time of the day.
If you’re among those who enjoy this type of service, just make sure you’re not replaying this documentary too close to mealtimes.
It follows Dr Michael Mosley as he turns himself into a living laboratory by infecting himself with all manner of nasties.
From a scientific standpoint it’s fascinating, and the effects of the parasites are sometimes quite surprising – but that doesn’t make the footage of him ingesting tapeworm-ridden cysts any easier to, ahem, swallow.
Also under the microscope are head lice, malaria protozoans, leeches and an unusual organism by the name of toxoplasma gondii, which is contracted from cat faeces and is said to make host humans take bigger risks. Not that Michael needs any more encouragement.
REALITY: 24 Hours in A&E (Channel 4, 21:00 - 22:00)

Registrar Ling has just started her shift. Working alongside Ling is her colleague and friend Claire, who's also a registrar.
David, who's 23, is brought to King's after having seizures uncontrollably for 30 minutes. David isn't responding to drugs so Ling weighs up the benefits of putting him into an induced coma to stop the seizures.
Meanwhile, in minors, 49-year-old Suzette and her grandson Azario have come to King's after Suzette was knocked over by a cyclist. While Suzette waits to be seen, four-year-old Azario races around A&E on his scooter, reminding visitors and patients to wash their hands.
And best friends Selin and Maria have come to King's after Selin cut her hand while taking the stone out of an avocado. While Selin has her finger stitched up by Dr Ling, she and Maria discuss what friendship means to them.
COMEDY: Outnumbered (BBC One, 9pm)
The art of all great sitcoms is knowing when to quit. So while the dynamic has changed in the Brockman household over the past seven years, what with many of the show’s kids now dwarfing the parents, Guy Jenkin and Andy Hamilton’s fab series is proving good to the last episode.
The rapidly growing youngsters are proving how independent they’ve become – not least Ben, who’s keen to show off his wilderness survival skills when he and his dad go off on a camping trip.
Meanwhile, Jake is facing a big decision about his education, and won’t shirk his responsibilities – unlike mum Sue, who is hoping to soon see the back of Stacey, Pete’s Australian goddaughter, who has severely outstayed her welcome in the household.
As ever, the cast includes Claire Skinner, Hugh Dennis, Tyger Drew-Honey, Daniel Roche and Ramona Marquez, while Emily Berrington guest stars as Stacey.
