What makes For example appear in the context? I don't understand why it came up in the text.
It is estimated that people age fifty and older spend about 48 percent of consumer dollars. They buy about 48 percent of all luxury cars, and they are responsible for about 80 percent of luxury travel. They even buy about 25 percent of all toys annually (there are about fifty-five million grandparents age fifty years and older in the United States). Nevertheless, marketing and merchandising programs commonly treat these customers as if they are much older. For example, there is the myth that older consumers are fixed on certain products and are unwilling to try new alternative products. Therefore, why should advertising of a new product be directed at older consumers? In fact, a survey of five hundred people over age fifty in shopping malls revealed that about 80 percent of them were quite willing to try new products.
