What can a person learn from an ancient person?

Modern man is wholly and completely dependent on the results of progress. He cannot exist outside the city or village. Many people on an elementary picnic cannot light a fire on their own, even with firewood and matches. People are accustomed to the various benefits of civilization. The art of survival must be learned from an ancient man. There were no benefits then. The food had to be obtained, not bought in the market. The fire had to be stored or obtained at any moment. People were much more resilient then. Hunger dictated courage.
