Grief is clearly very physical, too. I'm wondering what happens to the body during grief. We often suffer from insomnia, or alternatively, over sleeping. We feel disruptions toe appetite to mood. And i suppose at the limit, right, there are instances of individuals who suffer a really profound loss and that loss seems to play a role in actually causing them to die. It's not unheard of for a grieving to be such an assault on our bodies that it seems to be responsible, in some ways, for our own death.
