Some people go to work each day and then come home. They spend time with their family and friends. Maybe they watch TV or go to a movie. Sometimes they exercise or read. This is their life. But for other people, this is not enough. They look around their neighborhoods and see people with terrible hardships: sickness, loneness, and homelessness. Other people see problems with the environment. Many people want to help. They volunteer. They give some of their time to help others.
Volunteers help in many ways. Some visit sick and lonely people. Some give their friendship to children without parents. Some build houses for homeless people

Families in almost every country are changing. This is true in rich countries and poor ones. It is true in Africa, the Americas, Asia and Europe. All over the world, families are getting smaller.
In North Africa , in the past, many people lived in extended families. Fifty to hundred people lived together in a group of houses. These were all family members- grandparents, aunts, uncles, cousins, children, and grandchildren. But now this traditional family is breaking into smaller groups.
The traditional family in Mexico was also big. One generation ago, the average Mexican woman had seven children. Today, she has an average of only 2.5 children. Now , without so many children, families don’t need to spend so much money on basics, such as food, clothing and housing.

Many people wonder: Why do we sleep? Why do we dream? They ask themselves the purpose, or reason. There are many theories, or opinions about this , but scientists don’t know if these ideas are correct.
One theory of sleep says that during the day, we need sleep to make new chemicals and repair, or fix, our bodies. This theory is called the “ Repair Theory”. One piece of evidence for this theory is that our bodies produce more of growth hormone while we sleep.
Another theory is that the purpose of sleep is to dream. Dreaming occurs only during one stage , or period, of sleep ( Rapid Eye movement- REM )sleep. REM sleep occurs about 90 minutes and last for about 20 minutes. Some scientists believe that REM sleep helps us to remember things, but others don’t believe and don’t agree.
