My Son wants to join the Royal Navy. He is 23 years old and has not had Asthma since he was 11 yrs old. He goes to the gym 1 hr a day(5 days a week) He train for football which he plays on Saturdays. He has 2 jobs and is very fit. He went for a medical about 4 years ago to join the RAF, he was passed fit but did not want to join the RAF Regiment. He has just had his medical and the doc says that he has to do a Peak Flow Meter test for Asthma. Now he has to do this Peak Flow Meter test for the next 4 weeks and this will put he back.
