Reading the book, Born To Run. I am especially intrigued by the science of what biological and physiological traits provide human with a competitive advantage in nature even though we are not fast enough to outrun many of our potential predators. As the scientist broke down the possible advantages of the human physiology they stumble across critical answers once they ask critical questions in the opposite way.
Are you asking the same questions hoping for different answers? Try reversing your query. When the question is re-framed it may just reveal a completely different answer that may provide a new perspective.
