"Eliminate self-destructive behaviors. These concepts are self evident to most people (wear seat belts, don’t smoke or do drugs, don’t dive into shallow water) yet so many of us live our lives oblivious to impending danger. Develop a keen sense of awareness of your surroundings."
"Avoid poisonous things."
"Avoid exposure to chemical toxins in your food (pesticides, herbicides, chemicals, etc) and on your skin. But also try to avoid the hidden poisons in foods like sugars, grains, processed foods, trans and hydrogenated fats, and mercury in certain fish.
"Use your mind."
Exercise your brain daily as our ancestors did. Be inventive, creative, and aware. If your work is not stimulating (or even if it is), find time to read, write, play an instrument and interact socially."
