Back in the early 2000s when mobile phones started becoming common pocket fillers, there wasn't a week that went by that didn't feature a fearmongering headline about the dangers of these communication bricks.
Mobile phones were going to cook the brains of children, blow up while we slept or zap the male population's balls with deadly radiation.
While we're still waiting to see what prolonged mobile use does to the millennial generation, there are a growing number of studies that suggest that electromagnetic radiation from a mobile can slow down a man's "swimmers". If you keep your mobile in your front pocket, it could well be harming your fertility.
The best course of action? Wearing a jacket and leaving it in the pocket. Obviously. But for those who prefer having their phone nestled against their nads, there's the WaveWall.
This leather phone case claims to block all electromagnetic radiation given off by your smartphone thanks to a special lining.
According to the WaveWall's website, independent tests have indicated that their phone case reduces electromagnetic radiation by 85 percent - which is good news for anyone concerned about their chances of having kids in the future.
The top-loading leather pouch is available in three colours (red, blue and green) for £24.99.
But then, if you're the kind of person who lives in fear of gadgets and snacks slowly killing you, best skip the case, sell your phone and go live in a wood.
