LIVE LONGER LONG, LIVE LONGER HEALTH

A new study, led by David Cutler, Professor of Applied Economics, shows that life expectancy has increased over the past two decades, and people have become more and more healthy, longer.
The study is based on data collected between 1991 and 2009 on nearly 90,000 people who responded to the Medicare Current Beneficiary Survey (MCBS). Cutler has reported these results in working with Mary Beth Landrum at Harvard Medical School and Kaushik Ghosh of the National Bureau of Economic Research.
"With the exception of the 'year or two before his death, people are healthier than auna time," said Cutler. "In fact, the period of time in poor health came a few years before his death. At one time we used to see people with serious health conditions for the last six or seven years of their lives, but now is much less common. Elderly people have definitely better health. "
To understand whether people are getting healthier as the years pass, Cutler was first to respond to a question that, at least initially, it seemed impossible to solve: How far is it to the people from the dead? According to the author, the right way to calculate how long a person has left to live, is to do it retroactively. "When someone dies, you go back a year or two and we evaluate the health of the person"
"There are two basic scenarios concerning the end of life," he said. "According to the first medical science is turning into bulbs: in good health until, suddenly, you die. According to the other theory, however, life is a series of blows, and, thanks to medical care, we are able to deal with them and survive, but not always in good condition. E 'can therefore live longer, preventing death, but those years are not necessarily in good health, and are very expensive and socially. "
While researchers have tried to address the question of which model is more accurate, several studies have produced mixed results in competition.
For the future, Cutler hopes to unravel the reasons why some conditions are imposed today less today than in the past. Part of the change, he said, is due to increased access to care, the standards of which have also been improved, as well as a greater understanding of how to live a healthier life. "People are much more educated about their health now.'re Taking steps to prevent the decline in physical and mental / cognitive. Whilst we scientists do not yet have any way to slow Alzheimer's or Parkinson's disease, but there is much that can we do to other health problems. "
