64 is not old. I'll be 60 in April myself!
My son tries putting me in any nurseing home in 4 years and he'll have a real fight on his hands!

There are certainly a lot of ideas for helping those who need help, but I think the "approach" is the most important thing.
The first step is somehow convinceing the elderly mother that she needs help and therefore something has to change.
As long as she thinks she doesn't need to change anything, she won't coooperate with any of the ideas no matter how well intended they are.

My elderly mother is 79. Never drove, lives in a upstairs apt alone.
It's 13 stairs to get up there and takes her a good 15 min to do it cuz she has spinal problems, knee problems, muscles problems and to top it off her ankles are so bent they are nearly useless without braces on. The braces are built of lightweight material but still too heavy for her to lift her leg with them on. it's not a new problem but it does get worse all the time. Shes uses a Walker but for the stiars she uses one cane and banister. Her newest Walker is at the top of the stiars and the old Walker is at the bottom of the stairs.
I keep telling her this is a bad accident waiting to happen. She informs me she hangs on good and will never fall on the stairs.
She has been there about 29 years and is not into changeing.

For 2 years (YES 2 years) I have suggested, nagged, argued and begged her to let me find her a downstairs apt.
She says she can't. She has all kinds of excuses, financial reasons are logical and I do understand her reasons there, but the excuse she mentions most is that she has to "sort" her stuff before moving.. so the sorting is going mighty slow if you ask me.
I gave up and don't nag her any more.

Surprise.. my adult son suddenly has decided those stairs of his grandmas are too dangerous for her!
He is nagging me to nag her!

My siblings have hit the same stone wall I have in convinceing her.

BUT she is beginning to agree "sort of"
She has begun sorting out her personal library of books lately and had me take a lot to the Library Book Sale and and other stuff to the Goodwill. It's a step in the right direction. she has started agreeing with me about the stairs and admits she needs to move.

But she is gonna do it at her own pace..not mine. She is in no hurry.

So I believe that's the real problem.. convinceing the elderly to agree to the "change" you have in mind

My mother also won't wear one of those lifeline thingys.
She flat out refuses!

Her mind is fine (except she loves talking about the past).
So we can't force her to change.. but we are working hard at convinceing her.
I think the convinceing is the biggest hurdel.

Think out your reasons and methods for convinceing her.
Good luck.
