Important factors that determines the span of life on human

Understanding how insurance companies use the concept of life expectancy — and how it is calculated for the insured — can help you decide when to purchase a policy, how to calculate the future potential value of your policy and what to consider when choosing an annuity payout option.

Zimbabwe Actual life expectancy in Botswana declined from 65 in to 49 in before increasing to 66 in In South Africa, life expectancy was 63 in57 inand 58 in And in Zimbabwe, life expectancy was 60 in43 inand 54 in For example, white Americans born in are expected to live until age The greatest difference was 7.

This is largely due to economic clustering and poverty conditions that tend to associate based on geographic location. Multi-generational poverty found in struggling neighborhoods also contributes.

Life Expectancy: It's More Than Just A Number New research suggests that an important indicator of your probable life span may be your genes. Scientists have identified unique genetic signatures strongly associated with a long and healthy life, findings that could help to further the understanding of how certain genes may offer protection from common age-related diseases like cancer, dementia and cardiovascular disease.
Background Understanding how insurance companies use the concept of life expectancy — and how it is calculated for the insured — can help you decide when to purchase a policy, how to calculate the future potential value of your policy and what to consider when choosing an annuity payout option. The Hard Numbers Life expectancy is defined as the age to which a person is expected to live.

In United States cities such as Cincinnatithe life expectancy gap between low income and high income neighborhoods touches 20 years. For example, in the United Kingdom, life expectancy in the wealthiest and richest areas is several years higher than in the poorest areas.

This may reflect factors such as diet and lifestyle, as well as access to medical care. It may also reflect a selective effect: Tapia Granados and Ana Diez Roux at the University of Michigan found that life expectancy actually increased during the Great Depressionand during recessions and depressions in general.

Life expectancy is also likely to be affected by exposure to high levels of highway air pollution or industrial air pollution. This is one way that occupation can have a major effect on life expectancy. Coal miners and in prior generations, asbestos cutters often have lower life expediencies than average life expediencies.

Sex differences[ edit ] Pink: Countries where females life expectancy at birth is higher than males. A few countries in the south of Africa where females have shorter lives due to AIDS [57] Comparison of male and female life expectancy at birth for countries and territories as defined in the CIA Factbook, with selected bubbles labelled.

The dotted line corresponds to equal female and male life expectancy. The apparent 3D volumes of the bubbles are linearly proportional to their population.

In the uterusmale fetuses have a higher mortality rate babies are conceived in a ratio estimated to be from to males to females, but the ratio at birth in the United States is only males to females.

The difference in life expectancy between men and women in the United States dropped from 7. This may be attributable to the effects of infant mortality and young adult death rates. This is no longer the case, and female human life expectancy is considerably higher than that of males.

The reasons for this are not entirely certain. Traditional arguments tend to favor sociology-environmental factors: Some of these in the United States include: Some argue that shorter male life expectancy is merely another manifestation of the general rule, seen in all mammal species, that larger size individuals within a species tend, on average, to have shorter lives.

In countries such as Hungary, Bulgaria, India and China, males continued to outlive females into the twentieth century. With the exception of birds, for almost all of the animal species studied, males have higher mortality than females. By contrast, natural selection weeds out mitochondria that reduce female survival; therefore such mitochondria are less likely to be passed on to the next generation.

This thus suggests that females tend to live longer than males.

The authors claim that this is a partial explanation. Before death rates were the same. In people born afterthe death rate of to year-old men was double that of women of the same age. Cardiovascular disease was the main cause of the higher death rates among men.

Men may be more vulnerable to cardiovascular disease than women, but this susceptibility was evident only after deaths from other causes, such as infections, started to decline. Centenarian In developed countries, the number of centenarians is increasing at approximately 5. Shimane prefecture had an estimated centenarians per million inhabitants.

Life history theory Various species of plants and animals, including humans, have different lifespans. Evolutionary theory states that organisms that, by virtue of their defenses or lifestyle, live for long periods and avoid accidents, disease, predation, etc.

One theory is that if predation or accidental deaths prevent most individuals from living to an old age, there will be less natural selection to increase the intrinsic life span.

Support for the theory has been bolstered by several new studies linking lower basal metabolic rate to increased life expectancy. In a broad survey of zoo animals, no relationship was found between the fertility of the animal and its life span.One of the most important factors that determine a platelet life span is The platelets are one of the most important part of the human body where any abnormal.

Life expectancy is defined as the age to which a person is expected to live. It can also be described as the remaining number of years a person is expected to live, based on tables issued by the.

The exact duration of human life is unknown, although there is presumably a maximum life span for the human race established in the genetic material. At first thought, this statement seems irrational. Surely no human can live 1, years. Even though all may agree that the likelihood of an.

decline in life-expectancy rates in the U.S. is primarily attributable to major social and behavioral risk factors, increasing the support that life expectancy rates are. Factors affecting life expectancy include access to and the quality of health care, genetics, living conditions, hygiene, and diet.
