New Study Suggests There's a Limit To How Long People Can Live

Life expectancies have risen in many countries around the world thanks to breakthroughs in medical treatment and sanitation in the last century. The maximum age of death has also increased. But as these numbers continue to rise, it raises the question as to how long can people live? ABC News reports: The record for the world's oldest person is 122 years and the odds of shattering that record are slim, according to an analysis published Wednesday in the journal Nature. In the new study, researchers [at the Albert Einstein College of Medicine in New York] analyzed mortality data from a global database. They found that while there have been strides in reducing deaths among certain groups -- children, women during childbirth and the elderly -- the rate of improvement was slower for the very old, those over 100 years old. Next they examined how old centenarians were when they died. The record holder is Jeanne Calment, of France, who lived until 122 years old. Since her death in 1997, no one has broken her record. The researchers calculated the odds of someone reaching 125 years in a given year are less than 1 in 10,000. They think the human life span more likely maxes out at 115 years. Some aging specialists said the study doesn't take into account advances that have been made in extending the life span -- and health -- of certain laboratory animals including mice, worms and flies through genetic manipulation and other techniques. The goal is to eventually find treatments that might slow the aging process in humans and keep them healthier longer.
