The average age of the population of many countries is getting older. That means that businesses in those countries must adjust to older customers. In fact, many companies are working to respond to the special needs of the elderly. One example of this is the medical industry. New medicines and technologies are being developed especially for the elder people. Another business that offers services for the elderly is the tourist industry. Many travel agents offer special trips for groups of older people. And, finally, there are many different kinds of products made for the elderly. These include everything from shoes and shampoos to magazines and furniture.
