Your whole life is recorded and stored in your brain as conscious and subconscious memory. In addition, your brain contains the history of millions of years of evolution, as well as the characteristics and abilities that are unique to human beings.The future of all humanity depends on how well we use our brains. The brain is the greatest common denominator of humankind. If we all use our brain to pursue health, happiness, and peace, the lives we and our offspring experience on Earth will become much more meaningful and beautiful.
