3. Repetitive Stress Injury
The amount of texting some cell phone users do on a typical day would probably shock many people from older generations that did not grow up with cell phones. Though texting may be an efficient way to communicate with people, and some cell phone users are amazingly proficient at typing on those tiny keyboards, they are not immune to repetitive stress injuries that can cause pain, numbness, and general discomfort, particularly in the thumbs. These are certainly not life-threatening conditions, but some of them can be serious enough to warrant surgery. Making a voice call from time to time instead of texting will probably help cut down on the risk.
