Longevity, Life Expectancy and Statistics
Maximum Human Lifespan
What is the longest a person can survive? Maximum human lifespan has been a puzzle for researchers on aging; find out what different mathematical models predict for how long we can live.
Longevity Throughout History
How has the human life expectancy evolved through the ages? Find out how long our ancestors lived compared with today.
Evolution of Longevity
Groundbreaking research by Rachel Caspari and others have determined that humans began living significantly longer about 30,000 years ago, which represents the evolution of modern longevity.
Understanding Healthy Life Expectancy
Healthy Life Expectancy, also called HALE, represent the number of years, on average, a newborn can expect to live in full health. HALEs are useful for comparing the healthiness of different countries, not merely their life expectancy.
Disability Adjusted Life Years - DALYs - Measuring Suffering
Disability Adjusted Life Years for an illness measure the years of potential life lost and the years spend with disability. This information allows officials and researchers to compare the suffering caused by different health conditions.
Human Life Span
Life span is the maximum number of years an individual from a given species can live. For humans, that number is 122. No one has creditably lived longer that Jeanne Clament of France, who died in 1997 at the age of 122.
Years of Potential Life Lost
Years of Potential Life Lost (YPLL) measures premature mortality. By subtracting the age of death from the average life expectancy, researchers and officials can evaluate the public health impact of different diseases and injuries.
What are Cohort Studies?
Cohort studies use two or more groups of similar people to track the effect of a disease or an event. Find out how cohort studies give us clues into the aging process.
How Dangerous is a Broken Hip When You're Older?
Hip fractures are a major cause of disability and death in older people. Find out the mortality rate for people who suffer a broken hip, and whether they may live as long as someone without a hip fracture.
