Greg's getting electric for this one, as he tries out a tens machine. Tens (transcutaneous electrical nerve stimulation) is a type of pain relief which uses a mild electrical current. They're marketed at all types of pain - but do they work? The NHS isn't convinced yet. Listener Patrick is one of many who have asked about these devices, so we got in touch with a a professor who's studied them for 40 years. Also - another type of electrotherapy is a circulation booster. These circular devices claim to be able to help sore legs by activating the muscles. On behalf of listener Rick, Greg finds out what the evidence is for their effectiveness. PRODUCER: TOM MOSELEY

While Sliced Bread takes a break we serve up... Toast. A study of the spectacular failures of brands which had promised so much to consumers.     In each episode, the presenter and BBC business journalist, Sean Farrington, examines one big idea. What did it promise? Why did people back it? Why did they get burnt?   Some of the world's most successful businesses have also brought us some of the world's most remarkable failures. So, what led them to be toast? And what can we learn from their stories today?  Sean unpicks all the early optimism, hype and ambition. He learns about the tremendous success of a brand before hearing how it faltered, with help from expert commentators and people who were directly involved. How do they view things now and what, if anything, could have been done differently?  The self-made millionaire and serial entrepreneur, Sam White, is alongside him, analysing the missteps that changed a brand's fortunes and reaching her own, often instructive, conclusions.   From big tech to high street retail and, of course, food, Toast tackles the business ideas that, one way or another, ended up cooked.  Sliced Bread returns for a new batch of investigations in February. In the new series, Greg Foot will investigate more of the latest so-called wonder products to find out whether they really are the best thing since sliced bread. In the meantime, Toast is available in the Sliced Bread feed on BBC Sounds. Toast is a BBC Audio North production for BBC Radio 4.

Green Shield Stamps could be traded in for 'free' gifts so why did consumers abandon them?

This one's all about mushrooms - not so much your chestnut, button or portobellos from the supermarket, but more the likes of lion's mane, reishi and chaga. These much-feted fungi are claimed to offer all sorts of benefits, from relaxation to disease-fighting properties. We've had loads of questions about products containing them, particularly around mushroom coffee. Is there any evidence that it's better for you than your regular brew? Listener Leon is fond of it - and wants to know if there's any science to back up his inclination. To get him some answers, we hear from a registered nutritionist and a mycologist (fungi expert) who's just written a book all about medicinal mushrooms. So are they the best thing since Sliced Bread?
