The way of life that a group of people builds up over a long period of time becomes the people's culture. Culture includes the people's values and beliefs as well as their technical competency. Some aspects of culture are learned in a formal setting, such as a school, while other aspects are learned informally in the process of day-to-day living. A culture is always changing. Changes in s culture often come about by borrowing form another culture and by invention. To enrich the culture of our nation, we are constantly adapting new inventions and new ideas into our way of life.
