You know those studies that say butter is bad for you one week, but saying the opposite the next? Now those same unidentified gangs of "scientists" are gunning for our smartphones. A study from the United Chiropractic Association (nope, us neither) is claiming that when we lean forward to text and tweet, our hunched stance is taking years off our lives. The bad posture, it's claimed, is preventing us from breathing properly, which could cause cardiovascular problems later in life. The study's conclusion is that everyone should get their spines checked out by their local chiropractor -- which we're sure is in no way them just touting for more business. That said, on the off-chance that it's true, maybe we should all lean back a bit more the next time we're on WhatsApp.
