An estimated 20 million people throughout the world enjoy the lifestyle of naturism (nudism). It gives them a feeling of freedom and of being closer to Nature, which is important in today's age with cities of steel, concrete and little trees. There is nothing sexual about naturism; in fact, it reduces sex to its proper level. While a topless bar is an example of the exploitation of the nude body, naturism itself is more likely to prevent promiscuity, since it helps people accept themselves and others, and get over any hangups they have about their bodies.
