Summary: Life expectancy information, including health, physical and dietary factors that may increase human life expectancy in the future. The term "longevity" is sometimes used as a synonym for "life expectancy" - although the term "longevity" is sometimes meant to refer only to the particularly long-lived members of a population, while "life expectancy" is always statistically defined as the average number of years remaining in a population certain age. Differences in education, employment opportunities, lifestyle behaviors, social mobility and the wider local environment all have a major impact on male and female longevity. Where we live seems to affect how long we might live. Regardless of where we live, however, there are things we can do to improve our chances of living longer and healthier lives.

Definition of longevity and life expectancy

The term"Longevity"is sometimes used as a synonym for"Life expectancy"- however the term"Longevity"sometimes refers only to particularly long-lived members of a population, whereas"Life expectancy"is always statistically defined as the average number of years remaining at a given age.

Life expectancy at birth has increased rapidly over the past century due to many factors including falling infant mortality, rising living standards, improved lifestyles and education, and advances in health care and medicine.

Economic development and improvement in some environmental conditions (e.g. in many urban areas), improved lifestyles, advances in health care and medicine, including reduced infant mortality, have led to continuous increases in life expectancy at birth over the last century.

Important factors in life expectancy are gender, genetics, access to health care, hygiene, diet, exercise, lifestyle and crime rates. Evidence-based studies show that longevity is based on two main factors, genetics and lifestyle choices.

Gemini studies have estimated that approximately 20-30% of an individual's life expectancy is genetic, with the remainder due to individual behaviors and environmental factors that can be modified. In addition, it was found that after the age of 80, lifestyle plays almost no role in health and longevity, and that in old age almost everything is due to genetic factors.

Why do women live longer than men?

Females usually outlive males, and that was as true in pre-industrial times as it is today. This is due to smaller bodies (and therefore less stress on the heart), a stronger immune system (since testosterone acts as an immunosuppressant), and a lower propensity for physically hazardous activities.

It is also theorized that women have an evolutionary reason to live longer to help care for grandchildren and great-grandchildren.

Will you live longer if you come from a family that lived long?

Recent research from the Long Life Family Study (LLFS) confirms that major mortality-related diseases are less common in the families of long-lived individuals than in the general population.(Are members of long-lived families healthier than their equally long-lived peers - Evidence from the Long Life Family Study). An international collaborative study of the genetic and familial components of exceptional survival, longevity and healthy aging.

The researchers found that seven disorders were significantly less common in siblings in a long-lived family than in age-matched controls:

  • Alzheimer
  • hip fracture
  • Diabetes
  • Depression
  • prostate cancer
  • heart defect
  • Chronic kidney disease.

In contrast, the LLFS siblings were more likely to receive treatment for arthritis, cataracts, osteoporosis, and glaucoma. Spouses, descendants, and prospective spouses of these long-lived sibling ships shared significantly lower risks of Alzheimer's, diabetes, and heart failure. Thus, both genetic and environmental factors seem to play a role. With most offspring under 75, it will be intriguing to see if this early evidence of a health benefit in both genetic and marital relatives of long-lived families strengthens as the cohort ages.

Differences in education, employment opportunities, lifestyle behaviors, social mobility and the wider local environment all have a major impact on male and female longevity. Where we live seems to affect how long we might live. Regardless of where we live, however, there are things we can do to improve our chances of living longer and healthier lives.

  • Don't smoke, don't drink excessively, eat healthily and exercise regularly. This can add 10 years to your life.
  • Maintain and develop strong social networks with family or friends. Some studies suggest that this has a protective effect on health.
  • Take advantage of all the educational opportunities available to you in your adult life, even if you didn't do well in school. This appears to have health benefits.
  • Volunteering - There are likely opportunities to volunteer wherever you live, and some studies suggest it can help maintain mental health and improve life expectancy.

Some of the longest living people are

The Gerontology Research Group validates current longevity records by modern standards and maintains a list of super centenarians; There are many other invalid longevity claims. People who keep records include:

  • Sarah Knauss (1880–1999, 119 years, 97 days): The second-oldest documented person in modern times and the oldest American.
  • Christian Mortensen (1882-1998, 115 years, 252 days): the oldest man in history whose age has been confirmed by modern documents.
  • Jeanne Calment (1875-1997, 122 years, 164 days): the oldest person in history whose age has been confirmed by modern documents. This defines the modern human lifespan as determined by the oldest documented person to have ever lived.

While various other individuals have lived between the ages of 110 and 114, the above individuals are the only ones known to have lived longer than 114 years. Pre-20th-century individuals who lived to live 75 years or more include Benjamin Franklin, Thomas Jefferson, John Adams, Cato the Elder, Thomas Hobbes, and Michelangelo.

World Life ExpectancyStatistics

Life expectancies in different countries:

  • Developed countries: 77–90 years (e.g. Canada: 81.29 years, 2010 est.)
  • Developing countries: 32–80 years (e.g. Mozambique: 41.37 years, 2010 est.)

The longevity of the population increases with increasing life expectancy:

Will people live longer in the future?

The view of the U.S. Census Bureau on the future of longevity is that by 2050 life expectancy in the United States will hover in the mid-80s (up from 77.85 in 2006) and eventually peak in the low 90s barring major scientific advances possible to change the rate of human aging itself, rather than just addressing the effects of aging as is done today. However, recent increases in the prevalence of lifestyle diseases such as obesity, diabetes, hypertension and heart disease may drastically slow or reverse this trend towards increasing life expectancy in developed countries.

Some argue soMolecular Nanotechnologywill greatly increase human lifespan. If the rate of increase in lifespan can be increased to a level of 12 months per year with these technologies, this is defined as effective biological immortality and is the goal of radical life extension.
