Is it as high as that? That means you would expect two or three people in
each cricket team to be affected, but in all the time I have been at Cadnam
(over 30 years) only one person told me that they had a problem.

tested when I joined the railway). Perhaps many people either learn how to
deal with it

I once worked in a Brewery in the Town just over a couple of hills
from you. One chap I worked with arrived and promptly painted the
lovely oak paneling in his office bright yellow which we thought was
strange. Later in the week in he presented me with a 13 amp on a flex
without the top and asked "is this wired correctly?" He then
explained that he was colour blind and could not be sure of the
correct colours on the wires. It was a long time ago so it is possible
the flex had a green only wire.
Apart from that he seemed to cope quite well even though he was
actually a chemist and at some point in his career must have done
titrations etc.
