We are all creatures of habit. We can do most things without even thinking about them; our bodies take charge and do them for us. ~ Earl NightingaleIt is amazing how much of our lives are on autopilot. We do things without thinking. Consider your morning routine. Everything from waking up to making breakfast to getting dressed gets done unconsciously, or almost so. Our brains can be off doing all sorts of serious thinking while our habits take care of business.
Now, take those habits away for a week and replace them with nothing, say spending a week in a hospital. Those habits become foggy. The routine of nothing has replaced the routine of doing. When you get back to your life the first thing you notice is that you have to think about what used to just happen. What used to be automatic now requires conscious thought. It seems weird, even bizarre, perhaps even frightening like you have lost part of your mind as you consciously walk yourself through life's routines.
But it is perfectly normal. A few days back in your normal settings, hearth and home, and the habits reassert themselves. Life becomes routine again. Comfortable again. The brain can safely wander off again as your body gets back into the rhythm of taking care of itself.
This is one of the odd little facts of human life.
