Re the bit about Jews in my last post: orthodox Jews go to the other extreme, and hold formal mourning — "sit shiva", as it is called, from the Hebrew word for seven, as such mourning involving symbolic sitting on the ground with sackcloth and ashes, which nowadays means hiring chairs from the synagogue whose legs have been sawn short so that one is sitting lower than anyone else, lasts for seven days — if any of their community apostasises.

In other words, they go on symbolically as if they were dead, but do not actually make them so ~~ unlike certain other demographics in certain places...
