People can worry themselves to death, people die of broken hearts, old couples in nursing homes, one dies, the other goes minutes after, happens quite often here.
Concerntration camp survivors in their 90s, same for POWs and Vets they have a will to live, such a value of life that they refuse to die.
The mind is so powerful, Im sure we will never understand the brains ability to hit the on/off button.
Aboriginies here can "point the bone" at you. They believe that so strongly, its akin to holding a loaded shotgun to their head and pulling the trigger. If the bone is pointed at one of them, they curl up and die. Its a recorded fact. Doesnt matter what age, sex, health, dead in a week. Stare into space, close thier eyes and die. Its amazing that it can happen. Ifs thats not mind over matter, I dont know what is.
Horses can just throw themselves on the ground and die in a minute if they feel like it, thats incredible to see.
Anyone born this century wont die if they have enough money to pay for the regenerative cell treatments that will be ready in 20-50 years time. I think death will eventually become a choice, or the future of the poor. Now that the ban on stem cell research has been removed up there, anythings possible.
I can post a link to a podcast about placebos if you like.
