What causes so many senior citizens to have food sensitivities? Do our bodies force us to make better food choices as we age?

That will depend on your lifestyle prior to retirement. If you have become accustomed to eating in restaurants, being entertained regularly (theatre, cinema etc.) having regular holidays and other luxuries then those should be the first things to either cease totally or be cut down drastically as they are the ones which need a lot of money. If you are a smoker/drinker then cut them down with the view to cutting them out totally within a certain timescale.

If your tastes in certain foods are rather extravagant then - gently - change that. Try one or two non-branded goods and see how your palate accepts them. Even changing to non-branded goods for things like cleaning items and toilet rolls etc. will all reduce your bills.

If you have become accustomed to taking the car out even when just going to buy a newspaper then start walking OR don't even buy a daily paper. There is plenty of news on T.V. radio and the internet. Give this a lot of thought and do it gradually so as to not become depressed at rapid changes to your lifestyle.

Different people place importance on different purchases so your list will be completely different from another person's but starting on the expensive, non-essentials is the best place to start i.m.o. I've been there and actually enjoyed seeing how much I'd saved by doing this sensibly. I never found that it HURT but considered it a great achievement.

Now I don't even think about it. The money is in my account when a bill arrives and that make me happy.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
