I retired in 2015 from a thin blue line service after 43 years, no plans to do anything else quite content to do whatever I wanted when I wanted, tinkering with a sports car and motorcycle and anything else SWMBO wants doing. I don't miss the old job but miss some of the people I left behind. After a year of retirement I did start thinking I needed something else to do, found myself a casual job with a local funeral directors, not much money in it but it suits me and what I do make pays for my hobby vehicles.
Stepping into the Civvy world will come as a bit of a surprise they don't work like the Services, quite a culture shock but you soon learn their ways. I wish you well for the future.
