RAF. Thoughts of National Service addition

OldEric says :-) Before I applied to do my RAF National Service I was visiting our family doctor, Dr Byrne, in Milnthorpe a caustic Irishman but a very good doctor. I got along with him fine and he enquired what I intended to do now that I had left the Merchant Navy. So I told him my story.

In his direct manner he asked if I really wanted to do my National Service and before I could answer he followed up with "I could get you out if you want". I hesitated then I thanked him and told him no, I wanted the RAF practical experience to further my career.

What I didn't ask was how was he able to get me an exemption from my National Service. I've been intrigued how ever since.
