My penny's worth - my mildly ashmatic youngest son desperately wanted to join the light blues after his older sibling went off, eventually, to a place in the English Marches where only Jedi's live................... But several applications thru a fairly sympathetic Bristol RAF CIO met with the same predictable response - sorry, we dont accept asthmatics in any trade whatsoever at any time ever.
So, he applied to be a copper and is now happily racing around Plymouth in his government funded jam sandwich, still being paid by Betty and thanks Devon & Cornwall Constabulary for his eternal good fortune and eventual early retirement.
Move on my friend - you'll eventually learn that some battles are not worth fighting.
