JAF01 Lesson 12 Living Longer, Living Better?
I. Discuss with a partner:
1. Do you know any centenarians? Describe their lifestyle.
2. Do you think you will live to be a centenarian?
3. Do you think that world life expectancy will continue to increase? Why
or why not? What are the main factors affecting it?
4. According to researchers, people who live long lives stop eating when
they are 80% full, often work hard and maintain a positive outlook on
life. How do you think this helps them to live longer?
5. Rate the adjectives describing a personal quality on a scale from 10
(the most important) to 0 (the least important) for a long life:
sociable independent religious healthy wealthy relaxed intelligent
II. 1. Read the following passage and fill in the blanks with suitable forms
of verbs in brackets:
Average life expectancy __________ (increase) rapidly in the past decades. In
1900, the average world life expectancy _______ (be) 30 years. Since then, life
expectancy ___________ (increase) by about three years every 10 years, so that
the world average is now 67 years. The maximum human life span – that is, the
longest number of years a person _________ (live) – has also increased. In 1997,
Jeanne Calment of France died at the age of 122. So far, she is the oldest known
person ever to ________ (live).
During the twentieth century, increases in world life expectancy _________
(be) due to better sanitation, nutrition, medical practices, and healthcare. Today
scientists _________ (try) to help people live longer by studying genes. As they
learn how genes relate to health and aging, scientists may find ways to prevent
cancer, heart disease, and other common diseases. They may even be able to
slow the aging process. If genetic research ________ (be) successful, everyone
may someday live to be 120 years old.
6. Answer the following questions according to the information in the
passage.
- What is the difference between life expectancy and life span?
- According to the numbers given, what was the average life
expectancy in 1950?
- What are two ways that genetic research could help people be
healthier and live longer?
III. Examining graphic material
1. Study the graph below. What information does it show? Did any
information in the graph surprise you? Explain why.
Comparison of male and female life expectancy at birth for countries and territories as defined in the 2011 CIA
Factbook, with selected bubbles labelled. The dotted line corresponds to equal female and male life
expectancy. The apparent 3D volumes of the bubbles are linearly proportional to their population.

IV. Recording and calculating numbers
1. Scientists have identified factors that could make a person´s life longer or
shorter and developed calculators for one´s life expectancy. Listen and follow
the instructions to calculate your life expectancy.
2. Compare your total with a partner. Are your results lower or higher than you
expected? Is there anything you could change in order to increase your life
expectancy?
V. Reading
ADVANCES IN THE FIELD OF MEDICINE
1. Antibiotics
Injuries and illness can cause infections. In the past, these infections killed many people. For
example, over 20 million people died in the 1918 flu epidemic. Many of those people died
from pneumonia, an infection of the lungs, caused by the flu. In the twentieth century,
doctors and scientists developed a new type of medicine, the antibiotic. One of the most
important antibiotics was penicillin, which was first widely used during World War II. When
doctors treated pneumonia with penicillin, the number of deaths from this infection
decreased dramatically. Now doctors use penicillin and other antibiotics to treat a variety of
infections, so that fewer people die from infections today.
2 . Vaccines
The development of vaccines has also helped people live longer and healthier lives. Vaccines
and medicines that prevent people from catching certain diseases, such as smallpox,
measles, and influenza. Today, vaccines provide very effective protection from illness. One
good example is smallpox, which was a very serious disease in almost every part of the
world. Millions of people died in smallpox epidemics. However, there have not been any
cases of smallpox since 1977 because of global vaccination program that started in the
1950s. Other diseases, such as influenza, polio, and measles, still exist, but today fewer
people get sick and die from them because of vaccines.
3. Developments in surgery
Another reason people are living longer is the development of new techniques in surgery. A
good example is surgery to remove a cancerous tumor. In the past, most people could not
survive for a long time with this kind of tumor. Today, many people are able to live long and
healthy lives because surgery can get rid of the cancer.
Organ transplants have also helped people live longer. For example, in the past, people
usually died when their hearts failed. Today, they might receive a heart transplant and live
for many more years. Similarly, doctors are now able to perform lung, kidney, and liver
transplants.
It is true that antibiotics, vaccines, and developments in surgery have helped many people
be healthier and live longer. However, a large number of people in the world still die from
preventable diseases. For example, in 2002, more than 2 million people died from diseases
that a vaccine could have prevented. Many of those people lived in places where basic
medical care is not available. Others could not afford to see a doctor. If good, affordable
medical care was available everywhere in the world, it would be possible for even more
people to enjoy healthier, longer lives.
Answer each of the questions in your own words.
Explain at least one similarity and one difference between antibiotics and vaccines.
What is an organ transplant?
Why are some people not able to get good medical care when they need it?
