Life expectancies are increasing all over the world nowadays. Some of you probably know someone who is more than 100 years old. Before our next class, I want you to consider the following question: What factors do you think have contributed to the increase in life expectancy? Is it due to advances in medical technology, improvements in government services, changes in lifestyle habits, or something else entirely?

Lila

I think the main reason why people are living longer nowadays is recent advances in medical technology. Modern medicine has enabled us to better treat and manage chronic illnesses, and there have been major breakthroughs in areas such as cancer treatment and organ transplantation. As a result, people are able to live longer with diseases that may have been fatal in the past. Not only that, but they can live more rewarding and fulfilling lives than ever before.

John

While medical technology has certainly played a role, I think improvements in government services have been just as important. We now have access to clean drinking water, sanitation systems, and free vaccines that have dramatically reduced health problems. In the past, people didn’t have access to any of these things. Additionally, public health campaigns have helped educate people about healthy lifestyle habits such as exercise, healthy eating, and not smoking, which can also contribute to longer lifespans.

From my viewpoint, economic growth has an indirect yet significant influence on enhancing life expectancy. As economies grow and flourish, they often lead to better access to healthcare, improved living standards, and higher educational levels. These improvements are key to fostering healthier lifestyles and disease prevention. Enhanced healthcare services, a direct result of economic expansion, play a pivotal role in boosting overall health and prolonging life. Ethan's hometown experienced economic growth which led to the construction of a new hospital and the introduction of advanced healthcare services. With the economic upturn, his family and neighbors gained better access to healthcare, witnessing a noticeable improvement in community health. The local schools also received funding for health education programs, further promoting healthy lifestyles. This combination of enhanced healthcare and education in Ethan's community directly contributed to an increase in life expectancy, illustrating the positive impact of economic growth on public health.
