There are estimates that we daily walked for 10 - 20 kilometers for hundreds of thousands of years. The world's best problem solving machinery grew up under conditions of consistent, strenuous physical activity. It makes sense that when we don't recreate the environments in which the organ was forged, we get a loss of function. And that when we do restore those environments, we get that function back. The effects of aerobic exercise on executive function skills is a powerful empirical example of this idea.

Change often involves loss, so change can be a risky experience.

There are nature and nurture components to virtually every behavior a human experiences. The research effort lies only in finding the relevant percentages, not on some absolute value. That's one of the reasons behavioral scientists have to be really good statisticians.

They are trying to be productive at some of the most stressful times of their lives. What if companies took this unhappy collision of life events seriously? They could offer Gottman’s intervention as a benefit for every newly married, or newly pregnant, employee.

The brain processes meaning before detail. Providing the gist, the core concept, first was like giving a thirsty person a tall glass of water. And the brain likes hierarchy. Starting with general concepts naturally leads to explaining information in a hierarchical fashion. You have to do the general idea first. And then you will see that 40 percent improvement in understanding.

If you are curious, you won't be satisfied with the "tyranny of custom." People stuck in that rut might say "why?" and the first thing an exploratory person would say is "why not?"
