This is obviously the year of habits. #1 daughter pointed out that people with dementia, though they lose higher brain function, can still do the things governed by habit. The basal ganglia takes over and no thought is required.
So they can go to the same coffee shop each week and have roughly the same conversations. They can do routine housework and say conventional things. They may seem to be getting boring or self-centered or stubborn, but as long as they can continue in those habitual patterns, they’re okay.
Some of the habit stuff I’ve looked at claims that 40% of the average person’s day consists of mindless habitual routine. If that’s true, then people’s lives could just diminish to the habits they’ve developed.
So maybe we ought to develop a great collection of habits.
Or, of course, stave off dementia with plenty of exercise and vegetables.
