Entertaiment is an important part of the human existence. It helps in mental & physical relaxation. It gives a sense of belongingness to the society. It has a wide variety of forms. Some, like hunting and sledding, were necessary skills at one time, but have become entertainment. Others, such as fencing or archery, have developed into serious sports and even professions for some, while retaining their appeal to the general public as entertainment. What is entertaining for some people may be considered work by others, and some necessary skills, such as cooking, have evolved into competitions that are broadcast for entertainment.
