I have a friend who looks down on the Japanese aesthetic wabi sabi. It's the admiration of things that are old and used. At least, I thought it was. When I looked it up just now, the article in Wikipedia said that it was the acceptance of aging. I much prefer "the honoring and admiration of the appearance of usage, including scars, scratches, scrapes and wrinkles". I may have a tough time getting knowledgeable Japanese and philosophers of aesthetics to accept my definition. I admit I don't plan to work very hard at spreading my better word. I further admit that I was moved to write about this by my intelligent wife's clinging to the idea that scratches and wrinkles detract, and do not beautify.
