Too much texting can cause RSI (Repetitive Strain Injury) in our thumbs (大拇指) and wrists (腕关节). We spoke to a doctor called Harriet Wilson, who treats many patients with RSI. She says if we spend more than 10-15 minutes texting each time, we could have p in the future.
Dr. Harjeet Deepa, who treats RSI patients, said that the ypatient she had treated was a 5-year-old girl. She had s bad RSI in her hands that she couldn't hold a pencil.

Many university students and teenagers have RSI. If we don't do anything about this, too many young people could grow up in terrible pain.
