I disagree with a generalization here. A lot of women get even more focused on their appearance after age 60, right into their 80s. Crones don’t get to make a second impression!
My mom would talk about going into a retirement home, but it always came down to “but then I would have to get spruced up every time I went down for a meal”.
She passed away at home just the other week at the age of 95. But she had a neighbor gal come in once a week up until a few days before she died to look presentable.
