Horizon: Is Binge Drinking Really That Bad? (BBC2, 9pm)
It’s a common belief that it’s far better for you to enjoy the odd glass of beer or wine most evenings, rather than abstaining through the week and then binging on booze during the weekend. But how much truth is there in this theory?
Doctors and identical twins Chris and Xand van Tulleken put their bodies on the line by taking part in an experiment to investigate the effects that different drinking patterns have on an individual’s health.
Chris consumes his recommended weekly intake of 21 units of alcohol spread evenly across the week, while Xand uses up his allowance in single binges. How will their bodies differ after a month, and is it really any better for you to drink in moderation, rather than getting drunk?

The Job Centre (Channel 4, 10pm)
Not to be confused with ITV2’s similar sounding sitcom The Job Lot, this new documentary series follows Jane Vincent, the larger-than-life boss of Bradford recruitment agency, Candelisa People, her straight-talking team and the sometimes colourful characters who walk through their doors in search of employment.
In the first episode, the pressure is on for Jane’s newest recruit Phil as he handled a job that would allow him to hit his monthly target in one fell swoop, while his colleague Carlos discovers that one of the agency’s largest clients needs 60 workers, in just three hours.
Murder in Successville (BBC3, 10pm)
It may have taken us a little while to get grips with this comedy series, which sees an actual celebrity joining forces with DI Sleet (Tom Davis) to investigate a crime in a town populated by ’stars’, who are being impersonated with varying degrees of accuracy.
But now we’ve got to grips with it, it’s a lot of fun. This week, it’s the turn of Dragons’ Den veteran Deborah Meaden to investigate the poisoning of Lady Gaga.
Could the victim’s niece Lady Cheryl Fernandez-Versini be responsible, or should the cops be taking a closer look at her invalid aunt Nicki Minaj, retired scoutmaster Boris Johnson or butler Jay Z?

Robot & Frank (BBC1, 11.15pm)
(2012) A futuristic buddy movie about the unusual bond of trust between an ageing ex-con called Frank (Frank Langella), whose memory is faltering, and his VGC-60L robot helper (voiced by Peter Sarsgaard).
Frank lives alone and is slowly relinquishing his grasp on memories of the past, so the old man’s techno-reliant son (James Marsden) installs a servant bot to do Frank’s bidding. At first, Frank is reluctant to switch on the automaton, but eventually, can’t live without him.
This is an endearing slice of techno-life, anchored by a terrific performance from Langella as a cantankerous old coot who finds companionship when he least expects it.
Susan Sarandon, Liv Tyler and Marsden offer solid supporting performances as friends and loved ones, helping Frank through the fog of his twilight years.
