Why is ancient man more enduring than modern man?

The ancient people were hardy, but did not know about it. Lack of civilization, benefits, tempered man. Nature, climate, an urgent need to find food on his own influenced a person. If our ancestors were not so active, they simply froze to death in caves. There would be no large settlements, no progress. It is more difficult for a modern person, because there are many temptations, and robots do half of the work for them.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
