GALbaby, I believe in the Longevity Project it was revealed that parental divorce was a bigger factor in a younger death than parental death. It's definitely comparable in severity to death by that measure, though we treat death with so much more seriousness while divorce often cops a "you'll be right!" attitude (especially in Australia!).
