ABSTRACT
Our environment is surrounded by and is filled with many artifacts, some of which are visible and some that are invisible. You may have purchased a product recently, but many other artifacts may exist in your life and environment from the past. Some of the artifacts that you are using today may have been handed down by people living decades ago but they are reasonably acceptable in the context of modern everyday life. You consciously or unconsciously accept these artifacts because they have significance in your life. And you are living in this world today with a certain level of satisfaction surrounded by these artifacts.
