Life Expectancy, or longevity, is defined as the expected number of years of life remaining at a given age denoted by ex, which means the average number of subsequent years of life for someone now aged x, according to a particular mortality experience. In modern times, life expectancy has substantially changed on a yearly basis and cannot be used accurately for long-term predictions. The word "longevity" is sometimes used as a synonym for "life expectancy" in demography - however, the term "longevity" is sometimes meant to refer only to especially long lived members of a population, whereas "life expectancy" is always defined statistically as the average number of years remaining at a given age.
Quote: "The oldest confirmed recorded age for any human ever born is 122 years of age..."
Life expectancy is the average number of years of life remaining at a given age. It is the average expected lifespan of an individual. Today humans have an average life span of 31.99 years in Swaziland and 82 years in Japan. Our chart shows statistics for the average age you will live based on various world countries.
This is a question everyone asks at some stage in their life - How long will I live? When will I die? Life expectancy statistics is based on the average number of years of life remaining at a given age. Life span is the average expected years to live of an individual from birth. Our life statistics chart shows how long males and females can expect to live for in various world countries. (Age in years from birth to death)
The oldest confirmed recorded age for any human ever born is 122 years of age, though some people are reported to have lived longer there are no records to confirm these claims.
There are, of course, great variations in life expectancy statistics worldwide, mostly caused by differences in public health, medical care and diet from country to country. Climate also has an effect on what age you will live to, and the way data is collected can also be an important influence.
There are also variations between various groups within single countries. For instance significant differences occur in life span expectancy between males and females in France and many other developed countries, with women tending to outlive men by five years and over. These gender differences have been steadily decreasing in recent years, with statistics showing male life expectancy improving at a faster rate than that of females.
Poverty, in particular, tends to have a very substantial effect on life span expectancy. An example being the United Kingdom life expectancy in many of the wealthiest areas is currently on average ten years longer than the poorer areas and today the gap appears to be increasing as life span expectancy for the more wealthy continues to increase while in poorer regions of the U.K. there has been little increase.
Interestingly persons with serious mental illness tend to die, on average, 25 years earlier than the general public, with three out of five mentally ill dying from mainly preventable physical diseases such as Heart/Cardiovascular disease, Diabetes, Dyslipidaemia, Respiratory ailments, Pneumonia, and Influenza.

As can be seen by the chart there is still a large difference in statistics between average length of life in third world countries than in many Western countries today.
