We are both 61 and decided to both stop work at 60 but me and wife are diverging on issues of routine. Increasingly, over the last few years, I've been feeling that I don't want to eat at regular mealtimes, these days I would prefer only to eat when I'm actually hungry - so often I just can't face breakfast or I don't want to eat until say 8pm - frankly I'm not bothered when I eat - it's not something that's on my mind - it doesn't control my day - my mind odd on other things that I'm doing. I still like to cook and eat good meals - my appetite has reduced a bit but I rarely over eat anyway. I hardly drink alcohol - much as I love good wine, beer and lager - I can't even drink a while bottle of beer on my own - that doesn't bother me. We always used to want a cup of tea first thing in the morning but really I just couldn't care less any more - I don't even feel like breakfast most mornings - I'm happy to skip it and not easy anything until midday or just have a piece of fruit. If I don't eat cereal or porridge in the morning I'll sometimes prefer to eat that at night instead of a cooked meal. My wife prefers to stick to the routines we've had for decades and finds it very strange that I just don't feel like tea or breakfast in the morning. My sleep patterns have never been that good - I have never slept as many hours at my wife and really don't mind broken sleep or tiredness - it had always bothered my wife if she has a poor nights sleep.
This is not down to a loss of routine as I worked from home and was self employed for 12 years and have always done 90% of the cooking for instance.
I wondered if this was a relatively common change some people see as they get older: if not - is there another explanation?
