When a person's body shuts down, the person dies. Sleeping a lot, incontinence, disorientation, decreased body temperature, changes in breathing patterns, congestion and restlessness are some of the signs of the body shutting down.
A person whose body is shutting down might start to eat less, according to the Hospice Foundation of America. As the process moves forward, the person may start to drink less. By the end of life, the person may not accept any food or beverages at all.
On top of the physical signs of the body shutting down, there are some emotional signs that are often noticed. The person may start to withdraw from social interactions. They may start to make strange comments or even give permission for the others around them to move on.
