Mike, in your post you siad there was no suggestion of the A-word. If that is true and you were not diagnosed then your case is indeed different.
What you
must as PS says ask the
GP detailing the precise (as precise as the old drunk can, anyway) details of the case, for just that eventuality
. If he confirms that there is
nothing in your notes that refers to the A-word then there is no problem.
In you application you tick the No box. At interview you say No. Simple.
But you said
In year 7 of school (I must have been 11 or 12) during a long distance run I became quite out of breath. I was pretty good at long distance running
. You
were pretty good. As a precaution did you stop running? See the problem?
