The British and the Americans today live longer, marry later, have fewer children, and are more likely to get divorced than before. Young people leave home earlier, though not necessarily to get married. More women now go out to work, and more people, especially the old, live alone. The nuclear family (parents with perhaps two children) has largely replaced the extended family where several generations live together. Britain has one of the highest divorce rates in Western Europe: Approximately one in three marriages breaks up in divorce, half of them in the first ten years of marriage. As a result, more people are getting remarried and there are now over a million
single parents looking after 1.6 million children.Reading Skills Details: √Anxiety may show itself by such physical symptoms as increased heart activity or labored breathing.
