Have you ever wondered how long we as humans can live in this world? Some people live very long, don't they? So today we will talk about this term lifespan, as well as some other important words related to it. Knowing these will be very important for you and your family.
What is lifespan then?
Simply put, lifespan is the maximum amount of time a person can live. As far as is currently known, the maximum lifespan a human can live is 122 years. This is determined by experts based on the age of the oldest person in the world who can be accurately dated.
The current record holder is Jeanne Calment, a French woman. She died in 1997 at the age of 122. Imagine how long 122 years is! For men, this lifespan is a little shorter. The oldest confirmed man in the world is Jiroemon Kimura of Japan. He died in 2013 at the age of 116.
However, this lifespan is not the only thing that measures how long a person can or should live. There are other things, let's look at that too.
Are there other words for how long we live?
Yes, there are a few more words to talk about. You've probably heard these before. Let's see what they are:
- Life Expectancy
- Longevity
- Healthy lifespan (Healthspan)
Now you might be wondering what each of these names mean. Don't worry, let's talk about each one in a little more detail . Got it?
So what is life expectancy?
Life expectancy is the average age that a group of people, for example, in a country, can expect to live. People often confuse this term with the previously mentioned term 'lifespan', thinking that they are the same thing. But they are actually two different things.
Actually, no one can say exactly how long an individual will live, right? There's no way to predict it exactly. So, what experts do is take population statistics and calculate an average value based on that. That is, something like, "People in this country live this many years on average."
Your life expectancy can vary greatly depending on where you live. There are several other factors that can affect it. For example:
- Access to healthcare: This means the ease and ability to easily see a doctor, go to a hospital, get the necessary medication, and undergo surgery when you are sick.
- Access to nutritious food and clean water: Having access to good food and drink is very important for staying healthy.
- Whether there are sanitation services: That means things like toilet facilities, waste management, and a clean environment.
- Biological family history: Some diseases, such as diabetes and heart disease, can be inherited.
- Climate and the impact of climate change: Things like extreme temperatures, droughts, and floods affect health.
- Environmental regulations: Ways to protect yourself from things like air pollution and water pollution.
- Inherited or genetic factors: Some people may be born with a predisposition to certain medical conditions.
- Your medical history: Things like previous illnesses, surgeries, and medications you take.
- Whether there are public safety services such as the fire department and police: It is important to have someone to help in an emergency.
- War or armed conflict: People's lives are at greater risk in countries where there are such things.
Sometimes, global issues also affect life expectancy. Just think, the COVID-19 pandemic that began in late 2019 caused life expectancy around the world to drop for two consecutive years. By 2021, it had dropped to 71 years. That shows how much of an impact these things can have.
So what is longevity?
Longevity is the term for living longer than the `average life expectancy` we were talking about. That is, we say, "Wow, that guy lived a really long time, didn't he?" Those are the people who are said to have longevity.
The good news is that the number of people living longer than average is increasing around the world. In 2000, there were 152 million people over the age of 75. By 2023, that number will have more than doubled to 300.8 million! That means people are living longer than ever before. There are many reasons for this, including advances in medical science and better health habits.
Finally, what is a healthy lifespan?
Now look, with the advancement of modern medicine, people are living longer. That's a good thing. But, living longer and living healthily are two different things, right? Some people live for many years, but in the end, they can be very sick and have a hard time. That's where the concept of a healthy lifespan comes in.
Simply put, healthspan is the average length of time people can live in good health without developing chronic conditions, such as diabetes, heart disease, cancer, and age-related disabilities. Researchers usually use this to refer to groups of people, not individuals. For example, if a group of people has a longer average healthspan, it could mean that that group is in better health than other similar groups. Or, it could mean that health interventions, such as health programs, targeting that group are effective.
What is the current average human life expectancy?
By 2022, the worldwide average life expectancy was 72 years. This is more than double the average life expectancy in 1900! Did you know, back then, just over a hundred years ago, the average life expectancy was only 32 years! Isn't that incredible? That means we're living much longer now than people did in the past.
The average life expectancy for men is about 70 years. For women, it's about 75 years. Statistics show that, in general, women live slightly longer than men almost everywhere in the world.
However, this 72 years is just the average value for the world. It can vary greatly from country to country. For example, these are the five countries with the highest average life expectancy in the world in 2022:
- Macao: 85 years
- Liechtenstein: 84 years
- Japan: 84 years
- Hong Kong: 84 years
- French Polynesia: 84 years
The United States is in 64th place on this list. Their average life expectancy is 77 years. While the average life expectancy for men in America is 75, for women it is 80. So you can see how much this varies from country to country.
So what is the real difference between life expectancy and lifespan?
Now you probably understand the meaning of these two words, but let's explain a little more. Life expectancy is the average age that people can live. This average can vary depending on many things, such as where you live, your personal background, and your health habits. However, life span is the maximum age that people can live. So it is much longer than that average. That is, not everyone lives to the maximum age, but some people have the ability to do so.
Did you know that while the terms lifespan , life expectancy, and longevity are all used to refer to the length of someone's life, they don't always mean the same thing. You may not want to use these terms exactly as an expert or researcher would. However, it's important to know what they mean.
While these concepts cannot predict exactly how long you will live, they can help you gain some insight into your health. We hope that this knowledge will help you live a healthier, longer, and happier life.
So, what is the take-home message for us from this story?
We've talked about a lot of things today, haven't we? Lifespan , Life Expectancy , Longevity , and Healthspan . All of this is related to our lifespan, and how we live it.
The most important thing is to understand these and think about how we can live a little longer, healthier, happier lives. Because living a healthy and happy life is more important than just living longer.
- Think about your lifestyle: Eat a healthy, balanced diet. Get some exercise every day. Get enough sleep. These are the basics of a healthy life.
- Get regular medical checkups: This will help you identify any illnesses early and make treatment easier.
- Take care of your mental health: find ways to be happy, reduce stress, and spend time with friends and family.
- Stay away from bad habits like smoking and drinking alcohol. These are things that shorten your life expectancy.
Simple things like these can increase your health span and life expectancy . Remember, it's not about how long we live, but how well, healthily, and happily we live that matters. So, let's start working towards that today, right?
