People living in the country enjoy several advantages that people living in the city cannot enjoy.
They are in close contact with nature. They make friends with trees and stones,cows and dogs. They breathe fresh air. They fight with strong winds. They listen to the song of birds.
This contact with nature is beneficial to health. There are many diseases that are common in the city, but are not to be found in the country. For example, nearsightedness is almost unknown to country people.
People living in the country can easily get fresh vegetables, fresh fruit, and flesh milk. And they get them at lower prices than in the city.
Country people are mostly honest. They say what they mean, and make and keep promises with seriousness. They do not put on airs. They do not assume any manners common in what we call polite society.
