As the saying goes, "Change is not always for the better". Take social interaction, for example! We now live in an era in which many teenagers spend hours locked away in their bedrooms shooting virtual soldiers and hitting zombies over the head with digital baseball bats, while others sit home alone, chatting with friends, not in person, but through social networks. Teachers, politicians and parents have genuine reasons to argue that young people like this are in danger of losing the ability to connect with one another, to develop genuine relationships and to separate the fictional world of the Xbox or the Play Station from the real world. Others worry about the increasing breakdown of the family unit within the UK and link that to the increase of youth crime and antisocial behavior, or the problems that some young people have with drugs or alcohol. These issues are particularly common in areas of poverty and, in the light of the economic crisis, are unlikely to improve. Indeed, the gap between rich and poor in the UK could well increase, as unemployment figures rise and the cost of higher education increases. But being a teenager in the 21st century is not all doom and gloom, Young people in the UK today can enjoy living in a far more multicultural, integrated society in which opportunities are more equal and which is increasingly environmentally aware. They benefit from better child protection policies, a wider range of educational activities and clearer guidance on leading healthy lifestyles.  And as they grow up, this generation will benefit from huge technological inventions which will have an impact on almost every aspect of their lives, from entertainment to transport. They will see medical advances which could put an end to diseases like malaria and rid the world of AIDS. They will live longer, work smarter and they will even have a greater understanding of nature and the universe. What does the author think about life in the 21st century?
Life is going to get duller and simpler in the 21st century. There is both good and bad in life in the 21st century. Life will be easier because nobody will be out of employment. People will be healthier because there will be no diseases in the 21st century.
