A CMU study found that 22% of students, faculty, and staff report symptoms of repetitive stress injury (RSI). Harvard, MIT, and other universities are also reporting increased incidence of RSI. Students are learning bad typing habits in elementary school and high school. [Washington Post, 17May98. EduP.]

RSI comes from *repetitive* stress, especially small typing motions that don't lubricate your tendon sheaths. Use large motions, with frequent pauses. Keep your fingers curved and wrists straight while typing, and avoid click-and-drag motions of your mouse. Let your forearms float while typing, but use a wrist or forearm rest at other times. Don't keep any muscle tense for more than three minutes without a break, and stop every now and then to bend your fingers backwards or to shake your hands and restore circulation. (The traditional Indian "Namaste" greeting is a good hand stretch. Perhaps your computer will work better if you occasionally acknowledge the divinity within it.) You might also pull on your fingers occasionally to realign the joints. If trouble develops, try ice packs and slowly applied stretches, with warm-down stretches after typing sessions.

"Balance applies to our mind, body and emotions, to all levels of our being. It reminds us that anything we do, we can overdo or underdo." -- Dan Millman. [QotD, 19May98.]
