Like leonardo da vinci's word the sports needs a good research, researcher to act as a rudder or compass to go in a right track for the higher level performance.A sport is an organized, competitive, entertaining, and skillful activity requiring commitment, strategy, and fair play, in which a winner can be defined by objective means. It is governed by a set of rules or customs. Activities such as card games and board games are classified as "mind sports" and some are recognized as Olympic sports, requiring primary mental skills as well as mental and physical involvement. Noncompetitive activities, for example jogging or playing catch are usually classified as forms of recreation. Physical events such as scoring goals or crossing a line first often define the result of a sport. However, the degree of skill and performance in some sports such as diving, dressage and figure skating is judged according to well-defined criteria. This is in contrast with other judged activities such as beauty pageants and body building, where skill does not have to be shown and the criteria are not as well defined.
