To maximize your personal comfort:
Use a lighter touch on the keyboard to reduce shock to your wrists.
Use a document holder if you often type material from other sources.
Increase your lighting.
Periodically focus your eyes on an object at least 20 feet away.
Take a minute every so often to stretch and vary your routine.
Change your posture throughout the day.
You should perform 15 minutes of non-keying activity for every two hours of keying.
Do not cradle the telephone between your shoulder and neck while keying.
