Human Average Life Expectancy 115 Years ~ Check Yours

How long can human activity live? Can you live for more than 100 years actively? It is almost impossible to predict that low long a human being will survive or how long their body functionalities remain active? It varies from person to person. But the average life expectancy has increased significantly for a long period. It has become doubled for the last 2 decades.

Recently a scientific study shows that a human can live for 115 years. After this age, the brain activity starts drooping and finally stops its actions.

Another study explains that people of Japan, Western Europe, and North America are having an increased age of 150 years. The number of extremely aged people has increased significantly.

Greet Adrians-Boomgaard died (1899) at the of 110, he was the first identified supercentenarian.

Delina Finkins died (1928) at the age of 113 by breaking the previous super centenarian’s record. In 1997, Jeanne Calment passed away at the age of 122.

Life expectancy statistics :

Infant mortality reduces an increasing average life expectancy.

The mortality rate of the people (80 years or more than that) is reduced by almost 1.5 percent yearly. This fact is identified from 1960.

The progression in medical science made it possible. Other than that, the awareness of improved lifestyles, better education, healthier nutrition, and better living standard help people to live better lives. Thus, people can enjoy the increased average life expectancy and postpone death.

People can increase their life longevity by having essential drugs and cut off food consumption. This is scientifically termed as ‘calorie restriction mimetic’. This process is not yet scientifically proven.

The researchers are going on this fact that whether it is true or not. To date, it proves that there is no maximum limit for the human lifespan.

VO2Max Measurement –

VO2max is the measure of oxygen-flow to the heart muscles. This value drops along with increased age. Thus, the maximum age of a human can be measured by this value. When this value goes down than the required BMR (basal metabolic rate) from that point the maximum age limit can be calculated.

The required VO2max value is 3ml/kg/min. Based on this assumption, athletes have a VO2max value ranging from 50 to 60 at the age of 20, must have lifespans of 100 to 125 years.

This maximum age is also dependent on other factors such as the level of their physical activities. If they maintain a good level of physical activity, the declined rate of VO2max remained constant.

Life expectancy calculation :

A theory suggests that human life longevity (maximum) be nearly 125 years. This is done through an updated ’stretched exponential function’ for the survival curves of humans. This analysis of human body mass dynamics indicates extremums.

That corresponds to the mean (seventy to seventy-five years), the accepted maximum (hundred to hundred-ten years), and maximum (hundred-forty to hundred-sixty years) lifespan.

According to another research result, a human must have maximum life longevity. That limit started declining from the 1990s. But this result is disapproved due to biased sampling and coding error (simple).

This study supports a continuous increase in observed and theoretical upper lifespan of a human. The theoretical study also states that the maximum life-expectancy statistics of humans at birth are restricted by the life-characteristic value of humans. This is denoted by delta (δ). This value is nearly 104 years.

The United Nations undertakes projects on the average life expectancy of a human. According to the study, average life expectancy will rise to 106 years by 2090. This prediction is done in 2017.

This increased lifespan will occur through layered, ongoing, and dramatic consequences on world demography and population. Through the interval of this prediction is wide enough, the UN can’t become obvious on this hypothesis.

The modern prediction of Malthusian states that the demographical implications are greater for the human population at least for five centuries if maximum birth-rate or lifespan remains unlimited.

Average life expectancy Correlation with the capacity of DNA repair :

DNA damage (accumulated) proves to be the restrictive factor in the evaluation maximum life of a human. DNA damage is the sign of increased age. This is the major determinants of the maximum life of a human. This theory has become popular recently.

The human inherits deficiencies in genes of DNA repairing often initiate the aging process. The DNA damage increases and accumulates with age especially in mammalian tissues like kidney, brain, liver, and muscle.

A significant expectation from this theory, the damaged DNA repairing capacity should correlate with the life-span. It is found that the repairing capacity of nucleotide excision systematically increases with longevity.

This proves a stable and good correlation between the life-span and repairing capacity of nucleotide excision. Any defects in the repair protein of nucleotide excision cause premature aging in humans.

The breakage of DNA strands activates the PRAPs (Poly ADP Ribose Polymerase). This plays a significant role in the repairing of DNA based excision.  PRAP-1 is engaging in mammalian longevity maintenance.

Factors for maximum average life expectancy calculation

 1. Genetics –

The mortality factor and genetics are linking with each other. Genetics might be responsible for the maximum cause of death. CDC (Centers for Disease Control) published the list of primary causes of deaths,



Cardiac disease


Chronic respiratory disease

Pneumonia and Influenza

Cerebrovascular disease or stroke

Alzheimer’s disease

Suicide or self-harm

Kidney disease

2. Life expectancy by race and gender –

The female mortality rate is lower than the men at any age. Research results establish that general women live longer than men.

The common life expectancy of men in the US is 76.4 yrs, and at the age of 65 yrs, this becomes 82.9 yrs.

The common life expectancy of women in the US is 81.2 yrs, and at the age of 65 yrs, this becomes 85.5yrs.

The riskier behavioral pattern of men increases the rate of accidents than women.

3. Education –

The educational level is interlinking to the socio-economic status. This linkage increases the longevity of humans.

It is seeing that the 25 years old bachelor degree holders have increases life expectancy by 1.9 yrs for men and nearly 3 yrs for women.

25 years old high-school-diploma-holders have 9.3 yrs less life-expectancy than the bachelor holders.

Higher educational level increases the awareness of a better lifestyle. That improves the longevity factor of humans.

4. Childhood and parental conditions

The place of birth and bringing up environmental factors impact the lifespan in a wider way. The geographical areas and atmosphere are also dominant causes of fluctuation in the lifespans.

Poor conditions in the womb and early childhood also increase the mortality rate. This also affects the adulthood mortality rate.

5. Healthy life expectancy with a Balanced Lifestyle and improved medical technologies –

Inadequate exercise, excessive alcohol consumption, tobacco intake, unhealthy diet, food safety, risky behaviors, driving safety, and job safety are a few of the significant causes of a higher mortality rate.

Another poor lifestyle-related factor is obesity which also increases the rate of mortality.

Medical science is improving magically with time. The longevity of human life is increasing with the help of this advancement.

Especially the advancement in cardiac care, immunizations and antibiotics, organ transplant, imaging, and surgery change the way of treating people and gift them healthy and long lives.
