All of us apart from Tom suffer from hay fever.
George probably suffers the most. He sneezes and sniffles his way through May and June. We've never sought medical advice over it though, antihistamines keep it under control and manageable.
I never considered it a health problem.
Until Charlie took George to the RAF Careers centre recently.
If you suffer from hay fever the RAF won't let you anywhere near their aircraft.
It's a deal-breaker.
They don't want someone with streaming eyes flying their planes.
It's the end of George's ambition to be a fighter pilot.
However, there are plenty of exciting career opportunities for bright young people in the RAF that don't involve flying.
George has very sensibly resigned himself to the fact that he won't be able to fly.
And me? I am so relieved.
