A cultural impact differs from a personal conduct in that a cultural influence is simpler to modify. It is natural for people to change, and cultural influences do not determine our essential personalities, but rather our clothing. For example, if men started wearing skirts, this would be a cultural influence rather than a personal one. However, if men were to start acting like women or women like men, this would be personal behavior that could not be influenced by culture. Cultural influences can be good or bad, depending on whether they are local or foreign. Local cultures are those within one country, while foreign cultures are those outside of the country, such as those in Europe or Asia. Both local and foreign cultures have an effect on individuals who live within them. For example, the music industry in America has had a large impact on British musicians, because it has set the standard for what types of music are popular. At the same time, American musicians have also influenced their European counterparts with new ideas about music. People within each culture share certain values and behaviors that arise naturally after many years of living together. These shared values and behaviors are called cultural norms. Norms can be good or bad, depending on whether they are local norms or foreign norms. For example, drinking alcohol is a common practice in many countries around the world.
