God distinguished man from all his creatures and gave each of us a certain age to live, but have you ever wondered what is the average lifespan of a person? In this article, we will provide information on this subject and the method of calculating the average lifespan of a person, in addition to the difference between men and women with regard to age.

Have you ever thought about the average life you will live?

Did you research the average human lifespan?

Have you ever thought about some habits that can increase life?

Have you thought about whether longevity differs between women and men?

I think it is a set of available questions about raising an interesting topic, which is the average human lifespan.

Among the expectations is that most of us live to the age of 80, and others are challenging that some people have exceeded all expectations as there are people who lived over a hundred years, and in places like Okinawa, Japan and Sardinia, there are many centenarians, where the oldest person in history lived , a French woman named “Jeanne Calment” who lived until the year 122, when she was born in 1875, when her life expectancy was approximately 43,

If there is a change in the average human lifespan over the years, let us know it in detail.

## average human life

Usually, the average life expectancy of a person in a country is measured, according to the medical and health standards of that country,

It is possible that the age of the oldest people in the world is 115 years or older, and most of these records have been recorded in the United States, Japan and some European countries, where the usual retirement period is usually no more than 10-15 years, and as this explains The comparison is that it could be completely different in other countries.

note : The most expensive small countries again come to the fore in this ranking, and the ranking according to the development of the state all over the world

Hey, what is the average life expectancy?

Life expectancy is what refers to the estimated life expectancy of a human being since the time of birth, and this number of years is determined mainly by reference to current mortality rates.

In addition, given that these data take into account the past only, additional estimates are included in order to determine future age by reference to external influences.

These reasons could be environmental factors as well as developments in health care, so life expectancy is not a measured value, but rather a projection of the future.

Given the steady increase in life expectancy in the majority of countries, the true life expectancy of death may be slightly lower than expected and, depending on the country, it may be less than 2 to 5 years.

Above all, life expectancy is due to the result of the living conditions of an individual or a group of population, and the basic factors are, for example, good medical care, continuous and balanced nutrition and basic drinking water supply, all of these factors are greatly influenced by political factors, and that is The reason why life expectancy often derives from a state’s standard of living.

## How to calculate the average human lifespan according to the Gompertz equation

This oldest and most widely used method is based on calculating life expectancy, and thus, for life, by returning to the Gompertz equation, and this is the observation, made for the first time in the nineteenth century, that human mortality rates from diseases increase exponentially with The passage of time .

This basically means that your chance of dying, from cancer, heart disease, and many other infections and diseases, for example, roughly doubles every eight to nine years.

There are many ways in which the equation can be modified, and to account for how different factors (such as gender or even disease) affect life within a population, Gompertz calculations are even used for how health insurance premiums are calculated.

This is the reason why companies are so interested in whether you smoke, or if you are married and anything else that may allow them to judge more and more precisely the age at which you will die.

Another way to find out how long we can live is to look at the decline of our organs with age, and to run this rate of decline against the age at which they stop working.

For example, eye function shows this and the amount of oxygen our body uses during exercise forms a general pattern of decline with age, as most accounts suggest that organs will only function until the average person is about 120 years old.

However, these studies reveal the increasing variance between people as they age as well. For example, some people’s kidney function may deteriorate rapidly with age, while in others it does not change at all.

### What is the life expectancy for both men and women?

The average lifespan of a male child born in the United States is currently 76.3 years, and this places male citizens within the United States at 38th in the context of this ranking, on average.

American women are 5.1 years older, and may reach 81.4. Instead, the global average age of death is a few years lower at 70.6 years for men and 75.1 years for women, and within the European Union, these are 78.4 years and 83.8 years on average. consecutive.

The birth rate and also the birth death rate are given as deaths per 1000 people within one year.

### The difference between women and men according to age

In most countries, women are considered to be 4-8 years older than men, and this is according to the study of many scientists, and this is not a purely biological difference, and instead of this, it is attributed to different behaviors as well.

According to some other opinions, men are less concerned about their bodies than women, and in fact, smokers and alcohol consumers are more common among men, and physical stress also with a simultaneous aversion to medical treatments and health precautions is responsible for this, and in fact, There is an additional genetic reason for women’s longevity, too.

### What is the difference between mass lifespan and life expectancy

There are two different types within life tables: group and period

The collective life expectancy: is the average length of life remaining within a certain age, which people who were born in the same year experience,

For example, we can calculate the life expectancy of the cohort at 65 years of age in 2014 using the death rate for 65 years of age in 2014, 66 years of age in 2015, 67 years of age in 2016 and so on.

Life expectancy is the average length of life remaining at a certain age, and suppose that people suffer from age-specific mortality rates within a certain period from a certain age onwards.

Periods of life expectancy tend to be lower than the average life expectancy of the cohort, and this is because they do not include any assumptions about future improvements within the mortality rates.
