Chаpter 5 Relаtiоnships I 1Sоcieties gо through severаl stages in the production of goods. 2In many less developed countries, most people produce their own products and then consume them. 3As a society continues to grow, however, a person’s or household’s special talents are recognized. 4For example, one person may be very good at carpentry, one at baking bread, and one at growing vegetables. 5Soon an exchange process takes place: “I’ll trade you my bread or several loaves of it for the table and chair you’ve just built. 6Chances are, I can bake the bread better and faster than you can, and I know you can build tables and chairs better than I.” 7Eventually, several households begin to produce surplus products beyond their immediate needs. 8People produce more and more until they no longer have time to engage in exchange activity. 9They then turn their products over to one person or to a store that agrees to handle all further exchange activities. 10In this manner, a modern marketing system is created.

Chаpter 5 Relаtiоnships I Fаmоus pоets and writers have claimed for centuries that love stems from powerful emotions. However, research has shown that feelings of love are at least in part influenced by various chemicals in the brain. One group of chemicals that is just beginning to be understood are pheromones—substances that promote sexual attraction in the opposite sex. Experiments show that males release a chemical in their sweat that has been shown to be highly appealing to women—particularly during ovulation. Similarly, women produce their own pheromones that draw men’s interest—one actually can raise the level of testosterone in a man’s bloodstream. In addition to pheromones, another chemical, phenylethylamine (PEA), plays a crucial role in helping people fall “in love.” Related closely to the addictive stimulant drugs called amphetamines, PEA actually causes people to feel high from their relationship. The “heart-throbbing” sensations new lovers describe and the feelings of excitement and infatuation that are part of new relationships are directly attributed to this chemical. As with many addictive drugs, eventually the body builds up a tolerance to PEA and the strong feelings begin to wear off, usually within two years. This explains why infatuation cannot last forever. A third group of chemicals—endorphins—appears to be at work in long-term relationships. Endorphins are the body’s natural pain relievers. In addition, they produce a sense of security, tranquility and calm. During physical intimacy, endorphins are released into the bloodstream, creating the feeling of satisfaction and security common to long-term successful relationships.
