When I'm 65 I'll still be working 
And the younger people are the longer they will have to wait to retire.
You have a point there Rose. There have always been people who work longer than 65 but it can't be much fun for someone who, fo example, has to get on knees every day to mend washing machines to be forced to!
I get pension from my previous firm when I'm 60 (in three years) and one from where I've worked last 12years when I'm 65 but I like working and may want to carry on. That probably sounds greedy to some

but I get so much satisfaction from my jjob, can't bear the thought of retiring. Still no-one knows what's round the corner, all I hope for, for myself, is good health.
I could be useful working part time for a charitable organisation when I'm beyond retirement age but would be happy to donate some time especially on an ad hoc basis.
(Btw the organisation for which I now work has charitable status. The salaries are quite reasonable, not as much as outside the charity sector but I don't see any colleagues being unhappy about it. The job satisfaction is great and anyway we all have a choice.)
