Hello (N) this is Samuel again.
It’s all about keeping active and stress-free with any relationships with as little friction as possible. This is true for stopping any disease, and is good practical advice.
Anything you fight in life is something you may have to endure – there is a saying, ‘What you resist, persists.’
The mind is very important in that it gets you around and helps you to navigate your World. But to you, it is something you really don’t want to have taken in the form of Dementia. Each sense you have, including the mind, you may have to lose as you get older.
Whatever happens, you both will be taken care of – let it go, (N) – don’t let it be such a big thing in your life.
