At one point, as we get old, some things suddenly do not work as they used to. It takes more effort to lose weight, it takes more make-up to look pretty, you cannot drink as much wine, it takes a bit of pain to climb stairs or hills. And then we realize youth is gone. Some people take these news with great concern, and it takes some time to get used to the idea that you are over the hill. Some women complain about being invisible, I consider this a blessing. It should pass.
You know it's love when the pain of being apart is greater than the pain of being together.
