There is a long period of time when a person with dementia refuses care because "there's nothing wrong with me."

Also, using electronic systems, even while someone might be on-site to care for the person, can help discern patterns that might not otherwise be detectable.

There are other conditions, in any case, that would warrant some kind of remote "care" but not require daily on-site care.

This would all be terribly impractical today, but at least we can start to imagine how this data could be harnessed for specific use cases ... beyond the obvious applications for foodies.
