How long can you expect to live? That is to say, what is the average life expectancy for us?
The average life expectancy varies from country to country, but for many countries nowadays, the average life expectancy is over 70 years. That means that the average person will live to be at least 70 years old.
Actually, in the United States in 1980, the average life expectancy was 73.8 years. This age, 73.8 years, is a little higher than the average life expectancy in 1970. In 1970, the average was 70.8 years.
In fact, if you look at the average life expectancy information for this century, you'll see that the average gets higher every year. For instance, in 1900 it was 47.3, and in 1960 the average lifetime was 69.7 years. So, you can see that in 80 years the life expectancy has risen from 47.3 years to 73.8 years.
Why does the average life expectancy keep getting higher and higher? The main reasons are related to health care. First, health care, especially general health care for young children has improved steadily. Second, a large number of drugs have been developed in the past 40 to 50 years. These powerful drugs can prevent and cure many diseases that used to be fatal in the past.
