The world to the average joe back then was so mysterious and marvellous. People believed in story's of dragons, Sea monsters and ogres. Imagine not knowing anything about the world your imagination would be limitless. Exploring the world coming across lands you have never seen and coming back and sharing the stories to everyone. Some people not believing you because your story are so wild. Idk maybe i read to many fantasy works as a kid and now think about these things more than the average person.
Your idea of a person in the past is a person who lives in his imagination and lives off the happiness of the illusion of his thoughts, basically like a kid pretending he is spiderman and enjoys it so much.
In reality, out of any time in history, we have the best, we can travel anywhere in the world with ease and its cheap, we can discover anything we want, we have constant scientific discoveries, electricity and technology, spacecrafts, things people in the past couldn't even imagine, we have everything we desire, life is pretty good
whereas the average person in the past, would live a boring life, the food would be simple and not as amazing as it is now, they would have less variety, daily lie wouldn't be hectic, they would only be able to contact with family, and discoveries would be rare and only done by a few people, most of your life would consist of doing the same boring things for your entire life, get everything you have now, divide it by 100, that was there life.
In fact imagination and living in your fantasies is a sign of a boring life
