DNA

Science is working to gain more insight into human DNA, and the many mysteries that it could tell us. Not only physical and health attributes, but even down to how our thoughts, feelings, and personality are influenced by genetic information passed down generation to generation. If your ancestors had a good peaceful life with good memories,  this is passed down. If they had a traumatic life, this too is passed down creating a life influenced by those genetic memories. Perhaps this explains why some have a peaceful life, easy going and happy, and others have in varying degrees a unsettled life where they are offended by anything symbolic from the past, a past that ancestors experienced.  This would certainly help explain many things happening today.  It would also explain why mentally and emotionally, these two conflicting personality traits can not understand each other.
