Even in animal species, g(s). allow the transmission of experience to take place from the adults of a species to the young, and individual learning in groups. Human beings establish conventional rules that regulate these recreational actions. G(s). contribute to the development of the personality and the formation of habits, abilities and skills, making it a possible form of teaching. G. are of immeasurable heuristic importance. In industrial society, betting g.(s) called gambling are converted into a leisure industry for profit, leading many small business owners and salaried workers to financial ruin, and destroying their personality. This recreational activity is thus transformed into a social vice.
