I have a Godson who is 15 and wants to join the Army. He is very fit and a good rugby player, but had athsma as a child and still gets wheezy, usually around dust. He has not had an 'attack' since he was six, and the wheezing goes away on its own after a while, but he does use an inhaler to speed up the process. Will this stop him from joining up? He has had conflicting advice, and is not sure what to do.
