While living our lives in 21st century United States of America we sometimes get out of touch with those who went before us. The problems and challenges faced by our ancestors have not all disappeared. Many of the negatives faced in years past have just changed their skins, but underneath the surface lay the same basic issues for us.
Learn from those who preceded you by talking with those still alive and studying the lives and times of those who are gone. Both “good” and “bad” experiences can be opportunities to learn. Then teach it to your family and important friends so they can benefit from these experiences.
History is not dead. It is a continuous stream which carries you, your ancestors and your children.
