In a little book _Kinds of Minds_, Daniel Dennett commented that as we age our homes become "analog computers" for handling the needs and problems of life (and the joys, too).
Elderly persons removed from their familiar homes often show immediate cognitive loss, and if they are returned home, they usually regain the lost cognitive functions.

This is why I believe that if we want to age in place and stay capable of self care we need to proactively simplify and organize our homes to create and master our best possible "analog computer for self care."
The sooner the better.

I've mentioned my old friends who lived well on their own into their 80s and 90s: When I stayed in their home I was surprised how simple and uncluttered it was, just what was needed to live well and little more.
The memory inspires me to keep trying.
