At 50+ (well nearer 60) I am retiring after 38 years at the job, I ain't going to miss night duties, getting up at sparrow fart for real early shifts, I am going to miss a lot of good people and good times.
Would I like to be
starting in the job at my age? - No way!
At my age, experience and some good training early on with the likes of Heathrow Director have enabled me to keep valid to the end - the new 50+ bloke will have neither.
