Dude but what about the people who depend on these people? Some wives and children can't handle the loss and some have killed themself over such losses...
"Dude", every situation is different. And frankly, that's what makes it none of your business.
My grandmother was a walking zombie. She couldn't bathe, she couldn't talk, she didn't know *anyone*. She "lived" like this for 5 years. Had she known what was happening to her she would have killed herself.
All we could do was watch. You speak of loss. I think maybe you don't know what loss really is.
