Flossing just got a glow-up! Tufts University’s brainiacs have invented smart dental floss that’s basically a stress detector in disguise. This high-tech string slurps up your saliva, checks your cortisol levels, and beams the results to your phone. So, while you’re banishing plaque, you’re also getting a heads-up on whether your boss’s emails are spiking your stress. Talk about multitasking!
