My mother, who is pushing 70 has started a blog. I guess it's official, everyone has a blog now.
Her maiden post explores the phenomenon of late life divorce among everyone's favorite legalist heretics, the Mormons. It's an interesting read because my mother predates the baby boom, feminism and (I believe) the invention of fire and this gives her a unique perspective.
My own circle of acquaintances does not include many of the aged and infirm, so experience has led me to conclude that people get divorced because they are selfish egotists. Apparently older people get divorced for other reasons. Who knew?
