The U.S. Census Bureau view on the future of longevity is that life expectancy in the United States will be in the mid-80s by 2050 (up from 77.85 in 2006) and will top out eventually in the low 90s, barring major scientific advances that can change the rate of human aging itself, as opposed to merely treating the effects of aging as is done today.
The Census Bureau also predicted that the United States would have 5.3 million people aged over 100 in 2100.
The United Nations has also made projections far out into the future, up to 2300, at which point it projects that life expectancies in most developed countries will be between 100 and 106 years and still rising, though more and more slowly than before.
These projections also suggest that life expectancies in poor countries will still be less than those in rich countries in 2300, in some cases by as much as 20 years.
The UN itself mentioned that gaps in life expectancy so far in the future may well not exist, especially since the exchange of technology between rich and poor countries and the industrialization and development of poor countries may cause their life expectancies to converge fully with those of rich countries long before that point, similarly to the way life expectancies between rich and poor countries have already been converging over the last 60 years as better medicine, technology, and living conditions became accessible to many people in poor countries.
The UN has warned that these projections are uncertain, and cautions that any change or advancement in medical technology could invalidate such projections.
Recent increases in the rates of lifestyle diseases, such as obesity, diabetes, hypertension, and heart disease, may eventually slow or reverse this trend toward increasing life expectancy in the developed world, but have not yet done so.
Scientist Olshansky examined how much mortality from various causes would have to drop in order to boost life expectancy and concluded that most of the past increases in life expectancy occurred because of improved survival rates for young people.
He states that it seems unlikely that life expectancy at birth will ever exceed 85 years.
However, since 1840, record life expectancy has risen linearly for men and women, albeit more slowly for men.
For women the increase has been almost three months per year.
In light of steady increase, without any sign of limitation, the suggestion that life expectancy will top out must be treated with caution.
Scientists Oeppen and Vaupel observe that experts who assert that "life expectancy is approaching a ceiling ... have repeatedly been proven wrong."
It is thought that life expectancy for women has increased more dramatically owing to the considerable advances in medicine related to childbirth.
Mice have been genetically engineered to live twice as long as ordinary mice.
Drugs such as deprenyl are a part of the prescribing pharmacopia of veterinarians specifically to increase mammal lifespan.
A large plurality of research chemicals have been described at the scientific literature that increase the lifespan of a number of species.
Some argue that molecular nanotechnology will greatly extend human life spans.
If the rate of increase of life span can be raised with these technologies to a level of twelve months increase per year, this is defined as effective biological immortality and is the goal of radical life extension. 
Life expectancy is defined as the number of hours of operation for a lamp until 50% of them fail.
This means that it is possible for some lamps to fail after a short amount of time and for some to last significantly longer than the rated lamp life.
This is an average (median) life expectancy.
Production tolerances as low as 1% can create a variance of 25% in lamp life.
For LEDs, lamp life is when 50% of lamps have lumen output drop to 70% or less.
Lamps are also sensitive to switching cycles.
The rapid heating of a lamp filament or electrodes when a lamp is turned on is the most stressful event on the lamp.
Most test cycles have the lamps on for 3 hours and then off for 20 minutes.
(Some standard had to be used since it is unknown how the lamp will be used by consumers.)
This switching cycle repeats until the lamps fail and the data is recorded.
If switching is increased to only 1 hour on, the lamp life is usually reduced because the number of times the lamp has been turned on has increased.
Rooms with frequent switching (bathroom, bedrooms, etc.)
can expect much shorter lamp life than what is printed on the box. 
The Belgians are known to enjoy good health.
According to 2012 estimates, the average life expectancy is 79.65 years.
Since 1960, life expectancy has, in line with the European average, grown by two months per year.
Death in Belgium is mainly due to heart and vascular disorders, neoplasms, disorders of the respiratory system and unnatural causes of death (accidents, suicide).
Non-natural causes of death and cancer are the most common causes of death for females up to age 24 and males up to age 44.
Healthcare in Belgium is financed through both social security contributions and taxation.
Health insurance is compulsory.
Health care is delivered by a mostly private system of independent medical practitioners and hospitals.
Most of the time each provided service is directly paid by the patient and reimbursed later on by health insurance companies.
Belgian health care system is supervised and financed by the federal government, the three Communities and the three Regions, i.e.
six distinct Ministries (the Flemish Community and Region have merged).
In 1960, the average life expectancy of the world population was 50 years.
Forty-five years later, in 2004, life expectancy had improved by over 30% to 67 years.
Improvements in health care and the reduction in child mortality have led to a jump forward in middle-income countries, where life expectancy is now over 70 years.
In high-income countries life expectancy is now over 80 years, extending well beyond the traditional length of working life, causing social and economic problems.
It has led to people having an extra 4 hours of free-time during working days. 
 variation over time.
The following information is derived from "Encyclopædia Britannica", 1961. and other sources, some with a questionable accuracy.
Unless otherwise stated, it represents estimates of the life expectancies of the population as a whole.
In many instances, life expectancy varied considerably according to class and gender.
Life expectancy at birth takes account of infant mortality, but not pre-natal mortality.
Life expectancy increases with age as the individual survives the higher mortality rates associated with childhood.
For instance, the table above listed the life expectancy at birth in Medieval Britain at 30.
Having survived until the age of 21, a male member of the English aristocracy in this period could expect to live:  1200–1300: to age 64  1300–1400: to age 45 (due to the impact of the bubonic plague)  1400–1500: to age 69  1500–1550: to age 71 In general, the available data indicate that longer lifespans became more common recently in human evolution.
This increased longevity is attributed by some writers to cultural adaptations rather than genetic evolution, although some research indicates that during the Neolithic Revolution natural selection favored increased longevity.
Nevertheless, all researchers acknowledge the effect of cultural adaptations upon life expectancy.
During the early 1600s in England, life expectancy was only about 35 years, largely because two-thirds of all children died before the age of four.
The life expectancy was under 25 years in the Colony of Virginia, and in seventeenth-century New England, about 40 per cent died before reaching adulthood.
During the Industrial Revolution, the life expectancy of children increased dramatically.
The percentage of children born in London who died before the age of five decreased from 74.5% in 1730–1749 to 31.8% in 1810–1829.
Public health measures are credited with much of the recent increase in life expectancy.
During the 20th century, the average lifespan in the United States increased by more than 30 years, of which 25 years can be attributed to advances in public health.
In order to assess the quality of these additional years of life, 'healthy life expectancies' have been calculated for the last 30 years.
Since 2001, the World Health Organization has published statistics called Healthy life expectancy (HALE), defined as the average number of years that a person can expect to live in "full health", excluding the years lived in less than full health due to disease and/or injury.
Since 2004, Eurostat publishes annual statistics called Healthy Life Years (HLY) based on reported activity limitations.
The United States of America uses similar indicators in the framework of their nationwide health promotion and disease prevention plan "Healthy People 2010".
An increasing number of countries are using health expectancy indicators to monitor the health of their population.
