I read a great anthology of Chinese-Americn fiction but I csn't remember the title.
I can suggest mysteries if anyone is interested.
I've only seen myself in a story twice, a Bradbury short story and one of Jane Haddam's mysteries. There are astoundingly few stories about over 60 fat women so I don't expect it to happen again. Age is another of those things that seems to other people.
