[CQ-Contest] neckstrain/eyestrain/fatigue

[James Jarvis]

W2OX observed the growing number of bifocals in use
among contesters.  Even continuous gradient lenses
require a certain head position for a particular
focal length.  The resulting neck strain probably
also translates into strain along the spinal column.

Alex recommends a full set of 'computer glasses' for
contesting.  Focal length is roughly arms length...or
average distance to your equipment from your average
chair position.  This will give you maximum posture
flexibility, and minimize the strain.

I also recommend bowflex training with rowing,
as a means to strengthen the neck, back and abdominal
muscles.  The result of even moderate, repeated exercise,
is a definite improvement in ability to sit for long
periods.
