Athletics, also known as track and field or track and field athletics, is a collection of sport events. The word is derived from the Greek word "athlos" meaning "contest". It is a collection of sport events, which can roughly be divided into running, throwing, and jumping. Athletics has become widely spread within society and as a consequence brought with it many ancillary issues. Major areas of concern to society outside the pure competition include: steroid use, role modelling, sport psychology, public relations, and proper place within various levels of education.
