35 years ago, I was trying to get national ranking in beer drinking. Then, for some reason, I lost interest in volume and began to pursue quality instead. I'm not sure I achieved great heights as a connoisseur, but my tastes greatly improved and my intake dropped way off.
I just want to be healthy for my age or perhaps a bit better than that.
Preparing food for just one is always a problem to me. But it can be done. It helps to have a good grocery available. I did it by cutting up my own produce when I could and eating it up as needed, but when I couldn't do that, I could buy it already prepared for a bit more.
