Science has now proven what you've long expected (if you haven't experienced it for yourself): Walking while texting makes you slow down and weave like a drunk. Conrad Earnest and his colleagues sent “wexters” through an obstacle course to track their performance, and found that they took significantly more steps
, deviated from the path, and slowed down. The upside? They didn't bump into obstacles any more than regular walkers. But he says wexting could be a more significant problem for elderly adults, for whom a fall could have more serious consequences.
