I wish that was Mom's issue ... LOL ... I've been preaching to the choir by trying to get Mom to at least keep her phone with her at all times. She has an iPhone and it has no apps other than the ones that come with it, and she's deleted the ones that come with it that can be deleted ... LOL ... it is a smart phone that has had it's brains beat out ...
... but, if she would just carry it, at least she would be able to call if she fell and couldn't get up. Doesn't do much for her if she's unconscious, but, at least she would have a chance.
To her credit, I think the fall has "opened her eyes", at least some, now how long that lasts, who knows. We had a talk and I basically told her if she wasn't going to do what she needed to do to "keep" her independence, I would either take steps to take that away from her, I have total medical power of attorney, or, move out of my own house so that I didn't have to "see" her destroy herself.
Since that time, we have gotten her back on the little iPhone SE, small phone and lighter. She has had that with her pretty much 24/7 since she fell. I also got her a case that has a lanyard so she can wear it around her neck when she is in her "house coat" and doesn't have any pockets.
She has also been wearing her Medical Guardian device "most of the time", and that does include if she goes out, she's been good about that. She keeps telling me I don't need to wear that around here, I've got you to keep me safe. Now I simply respond by saying, "How'd that work out for you on 05/09/2020 when you fell and spent 3.5 hours on the ground in the dark?" Of course, that always ends the conversation, because she knows she's lost. But, there has been some progress. We'll see if this lasts ... only time will tell.
