Does Body Size Affect Longevity?

For so many years, the phrase “bigger is better” made people work out to have bigger muscles and bones. In fact, a lot of people are encouraged to drink milk every day just so they can grow taller.

But is there a direct relationship between people with big bodies and having longer lifespans?

Life Expectancy in Australia

In a report published by the Australian Institute of Health and Welfare (AIHW), it says that both men and women have longer lifespans today as compared to those who lived during the 19th century.

The report also claims that males can live to an average of 80 years old while females can live up to 84 years old.

This report also shows how Australians fared against other country’s lifespans. In Japan, males had the same average lifespans to those in Australia.

In Korea, females also had the same lifespan to Australian women. Compared to European countries, both male and female Australians also have almost the same lifespans with 1-2 years difference.

The Connection between Longevity and Body Size

Based on the reports of the AIHW, one can conclude that longevity does not directly affect the lifespan of people.

Asian men and women are relatively smaller in size as compared to Australians; however, the reports show that they still have the same average lifespan.

But there are also studies that show that smaller people live a longer life. In fact, if you watch a few documentaries about the Asian culture, you will see that it is not uncommon for the people to reach over 90 years old.

Although, some would argue that they live longer lives not because they are smaller, but because of their culture, their eating habits, and their surroundings.

What Affects Longevity?

By now, it has become clear that longevity is not a product of body size. If it is, body size then is not the only factor that helps a person live to a hundred years old.

Scientists and doctors claim that a longer lifespan is determined by the lifestyle and health of the person as well as their access to health care.

One determinant of longevity is the amount of time spent on exercising. People who allot at least 30 minutes a day have a higher chance of living a long life.

This is because exercise has a lot of health benefits that include stronger bones, muscles, brain, heart, and lungs.

As a person grows older, these daily exercises will reward with their benefits because he or she will be less prone to catching chronic diseases.

Another factor that affects longevity is access to health care. In Australia, health care services are abundant since the government is able to provide free medical services to residents who get checked in public facilities.

To add to that, there are also subsidies for different types of treatment. Since Australians are able to get checked relatively easier, the risk of discovering a disease at an untreatable stage is lower.

In conclusion, body size does not affect longevity. It may be an advantage to a lot of people, but longevity is determined by other factors both external and internal to the person.
