Very interesting topic and one I too have started to look into. My husband is having issues and I may soon have to put him in assisted living or a nursing home. The last thing he did was to start a fire in the kitchen because, since he hurts a lot he doesn't always focus on what he is doing, and caught a potholder on fire. Didn't realize he did it and left kitchen!! I smelled something burning and caught it totally ablaze and was able to take care of the incident before it got worse. We do have a large area on kitchen ceiling now from smoke.
