i used to work in a hospital and washed my hands all the
time..i got in the habit and still do..at work i would
wipe my keyboard,phone and desktop with alcohol pads when starting my shift..
after dealing with people who had any kind of URI i would
do the same thing and not use any pens i lent them..i went
many winters without picking up any kind of cold..
same on camping trips..i make sure my hands--if nothing else
are clean..
