Personally,after getting up at silly o’clock and working like a good’un with weeks away from home for over 50 years,why the hell would i want to continue now if i don’t have to.Ok,for many people who have a limited income [due to the kindness of successive governements] 
,who are more or less forced to continue working there is Little choice but if you have sufficient income there are many things to do with your time,and who knows how much there is left.This has been discussed Before on here and there are many who continue to work so it is,in many cases a personal thing.
