I am very much for euthanasia and assisted suicide for the terminally ill. I have also already spoken to all my loved ones, and have told them to pull the plug on my if I ever end up in a vegetative state.
I don't think it's fair to force people to suffer day after day. Some people just don't want to hurt anymore, and they don't want to put any more financial strain on their families. Why do we force people to continue living half lives? People aren't meant to live forever. It's great that we have all these medical advances in society, but someday we are going to have to stop being so terrified of death, and realize that death has it's place and purpose too.
