Some science bods reckon they've solved the debate about where to keep your ketchup

Where do you keep your ketchup? Some people keep it in the fridge, others keep it in the cupboard. The odd weirdo keeps it out on the kitchen top, and I keep it in my bedroom, where I keep all my condiments and spreads. Once a flatmate caught me eating peanut butter straight out of the jar with my fingers whilst lying on my bed – I’d honestly rather he’d caught me having a wank. It was a low point.
