IMPORTANT
=========
TTYPE was written in the early 1980s, before widespread
awareness of what is now a major health hazard to white-
collar workers: repeated stress injury.
RSI can destroy your ability to earn a living by
depriving you of the use of your hands. It can be very
painful and require costly surgery.
As a beginning typist, you run little short-term risk,
because RSI is a problem that builds up over the years: As
its name implies, it is damage that results from repeated
stress over a long period, such as stress on your hands and
wrists.
But now is the time to develop good habits to prevent
problems:
-- Sit comfortably, in a good chair that provides
support for your lower back. The height should be adjusted to
be comfortable, without placing pressure on your thighs.
-- Your monitor screen should be a comfortable distance
from your eyes, with the top of the screen slightly below
your eyes.
-- Keep your wrists straight while typing, not at an
angle that could put pressure on the nerves that pass through
the carpal tunnel in your wrists. Cushioned wrist rests are
available to help.
-- Do not bend your wrists to reach cursor or function
keys, or other keys that are outside of the main typewriter
area. Move your entire hand.
-- Do not pound on the keyboard. Learn to press enough
to get the computer to respond.
-- Your elbows should be at approximately right angles
as you type. This requires your keyboard to be at a
comfortable level.
-- Take frequent breaks: Stand up and stretch. Look
around the room. Let your eyes refocus on distant objects.
-- IF YOU EXPERIENCE PAIN OR NUMBNESS, SEE A DOCTOR. RSI
is a recognized occupational health hazard, and treatment is
covered by your employer's occupational health policy.
The consequences of RSI can be extremely serious. Don't
ignore symptoms. To do so would be like allowing someone to
cut your hands off on an installment plan: Your health and
your livelihood are at stake.
