Exactly - there are things that I would change now to make sure I make thing easier for myself and - more importantly - easier for the people around me.

Those plans should be in place regardless of the results of a blood test

I think there are many people (myself included) whose plans would change dramatically upon discovery of Alzheimer's, dementia, or some other degenerative disease. I might consider moving to somewhere with more liberal assisted suicide laws for example.

No, they shouldn’t. Makes no sense to plan for living with a mental disability if you’re not close to needing it.

I am absolutely not going to plan on a care facility right now. That sounds absolutely bogus.

Yes, like walking out into the woods before it gets too bad.

Like what? You should already have a will, life insurance, etc. even without the disease. All you're doing by knowing earlier is causing psychological harms to yourself and the people you tell, adding more years of anxiety, grief, and sadness for no gain. Think about the bigger picture.

Downsizing your house? Picking your long term care location? Changing your asset balance? Recording more photos, audio, and video?

Knowing an early, painful fate allows you to approach it with dignity.
