i'll nvr forget what my recruitment officer told me...
"maybe u get pp1, then maybe at the end of ten years, u realise u
sick of army, ORD late twenties, hard to get job. Why not u sign
short term contract, 5 years, finish liao still got money take and
your youth still there?" 
Those arc guys could sell ice to an eskimo man...
but if given a choice, i'd rather join the civil defence than army
medic...
