How on earth did those typists manage with three hights of keys, no wrist
pads and having to put even force behind the key's.
Wrist pads ? Bad idea! If you watch the old films you'll see that the
typists work with arms out and wrists floating so no contact between the
wrists and any surface, much like a concert pianist.
Try using one of those mouse mats with the (ahem) ergonomic foam wrist
rest day after day and you'll find that your hand will lock up or will
tingle after several days. Soft as they are, there's still a point of
contact where blood flow is decreased between the arm and hand and this
does not bode well for the user, long term.
Tear that blob off the front area of the mat, keep your wrist from
lazily wresting on the surface and you'll find that your hand and arm
troubles will go away.
