I'm almost 65. I have a full on, professional job working about 50 hpw. I also have a substantial home to run with a very large garden. I am relatively fit and pain free despite severe osteoporosis.
Over the last year I have found I have to pace significantly. If we have the family home for the weekend with lots of catering, nowadays I need Monday off as otherwise I am utterly shattered the following week. Similarly, we don't do a midweek dinner or opera/theatre trip any more.
Add in two very frail mothers who need very frequent visiting and full-time work is no longer sustainable.
I am reducing to three days a week after the summer. Never thought I would feel the need to. Sometimes after a full time, full on week it feels as though my brain has run out of space.
We slow down and it creeps up. Rather like being 36 weeks pg when at 34 weeks you thought you could do a day's work before going into labour.
Fortunately, I can cut down from a financial perspective - I'll see how long I can keep going part-time.
Also a dear friend of ours retired at 66 last year. Three weeks later they were diagnosed with acute myeloid leukaemia They just reached 67. I have worked very hard - I want some quality retirement.
