As nobody else has said it then,
good luck <g>
if you make it then I hope you enjoy it - becoming an AEOp* changed my life dramatically, and I have no doubt whatsoever that if you get through it all then it will do the same for you....you WILL be a different person x years down the line, and when you are an old git like me you'll look back on it all and decide, without a shadow of doubt, that you'd do it all again given the choice.

*WSO/WSOp - back in my day the old gits wore an 'S'...don't panic, inside 5 years you too could have an equally valid marker to denote that 'I've spent longer in NAAFI queues than you've been in the airforce' sensation.
