Corn

The current documentary, "King Corn", points to a basic human trait. Human beings are prone to laziness. Corn is the easiest grain crop to grow and use for many different applications, despite its nutritional inferiority to other foods.

Western civilization, rapidly becoming world civilization, is dependent on a corn economy in the same way it is dependent on an oil economy. Both of these dependencies are toxic and potentially lethal for the human species and even the entire planet.

Individual practice of human evolution requires reducing or eliminating corn products and oil products from one's individual life. If you attempt this, you will find it very difficult. However, you will also find it may extend your life and also improve its quality in every moment.
