Not to derail, but an aside: Friends of ours in Florence. They are both in their 80's. He has bad knees and a bad back, needing help getting around. She was somewhat healthy for he age, but struggled to manhandle him. He's a good size fellow. They have 3 kids, scattered around the southeast. The kids each had a time they called daily. One day recently, they could get no answer. The child that lives nearby went to check on them. She entered through the garage and could hear him yelling for help. She found them at the bottom if the basement stairs.

They were trying to go downstairs and, for whatever reason, she was below him. He fell, taking her down the steps. The fall broke her neck, killing her instantly. It also broke his back. He laid on top of her for several hours, unable to get up. He was unable to attend her funeral. I hunt in some remote places by myself, but I carry a Garmin satellite unit with an SOS feature. That evening, I started the same search you are now doing for my parents.
