I did a full career of 37 years as aircrew and was then invited to stay as a reservist under the old RO scheme. After a further 14 years, due to a change in family circumstances, I eventually retired after 50+ years in blue.
I retired to run a business in an overseas country, which keeps me very busy. After so long in blue I was surprised that the transition was so painless. I do not yearn for the "Good old days", but do sometimes think about them, mainly with affection.
When I can ,I meet up with other old friends/reprobates to chew the cud.
Life goes on and you will survive, but for the Service itself you are the "hand in the bucket of water, take it out and no hole remains". However keeping contact with old friends and colleagues is still important,
Best of luck for the future!!
