It can save your family a lot of suffering and strife. Today my mother-in-law strode out of the house and headed down the street. She got almost to the very busy route 201 before the respite-care worker managed to slow her down until my brother-in-law's girlfriend helped corral her and get help to get her into the car and take her home. The respite-care people are not trained or allowed to use physical restraint. My mother-in-law is ~95 and physically healthy, but badly demented. Two-three of the siblings insist on keeping her at home, but it is increasingly evident that she needs to be in a nursing home. 4-5 siblings are now willing to get her into a nursing home, but the conflict is tearing the family apart. We have people in their 50s and 60s at each others' throats. People who used to love to get together at the family camp for holidays, and who would do about anything for each other. If you don't have a living will, make one. If your parent doesn't have a living will, please encourage them to make one. Some aspects of my life are a hell because I'm watching this family getting torn up over a lack of planning and clear intent. This spring/summer has been especially stressful, because my wife has been under undue strain, and there is nothing that I can do to help.
