>> that is amazing. dr. ashton, i have another facebook question for you. debbie wrote to ask, do you think texting could cause carpal tunnel syndrome? >> well, the answer to that one, harry, is it possibly could. this falls under the category of an overuse injury. we've heard of blackberry thumb or cell phone elbow. any repetitive action, anything you do over and over again for hours and hours a day can affect your body. so, when you're talking about texting or on the computer, thumbs, wrists, elbow, neck, can all become effected. >> is treatment approved for that? >> have you heard the saying from your doctor, doctor, it hurts when i do this, and the doctor says, stop doing that. so the answer is rest and intervene on that repetitive action. stop doing it. >> jack, we've got a tweet asking, if someone creates a twitter account or a facebook page claiming to be me, not me in particular but the viewer, can i sue them?
