While the average human life continues to increase, prostate poses a great challenge: give more quality to old age. Where science aims?

Human life shows no sign of approaching a fixed limit imposed by biology or other factors. With a 7 billion people, recipe the world's population and record, and this is mainly due to the increase in life expectancy at birth, namely, estimate at birth on how many years we will live.

According to current demographic data, that Life expectancy has nearly tripled throughout the history of mankind. Further: in the last 200 years old, within 10 generations, doubled.

The initial way to that extension has been marked by a general improvement in the standard of living, and organized efforts to control the spread of infectious diseases, and a reduction in infant mortality in the late nineteenth century and throughout the twentieth century.

From 1970, y differentiates for previous seasons, the main reason for the increase in life expectancy was the reduction in mortality rates in the elderly population. In particular, contraction of mortality associated with cardiovascular disease, stroke or stroke and cancer.

According to researchers at the Department of Demography at the University of California, historical complexity and stability of the steady upward trend in the average life suggest that, at mid-century, life expectancy at birth in the industrialized countries will be about 85-87 years old. While the average age of the world population has spread over time, the maximum number of years lived has not been overcome since, in 1997, Jeanne Louise Calment died at 122 years old, en Arles, France. Despite this irrefutable fact, Thanks to advances in the fields of molecular biology and genetics is possible that those who read these words today are living the historical threshold at which the fundamental mechanisms of aging process unravel. Tal vez, in the not too distant future, your children or your grandchildren can bring about interventions that prolong their lives to levels never achieved.

We all age from the moment we are born. In the first century, Galen introduced the concept of aging is a loss of productivity, described as the depletion of the fundamental humours of blood and other body fluids. He theorized that this was not a disease, but a process that gradually develops from birth.

However, now know that aging is a continuous process of human growth and development, full of potential, highly modifiable by a combination of personal responsibility and appropriate medical care. Not all age the same way. Just as every life is unique, every person who reaches old age makes his way, with their particular features. It is these unique characteristics that define the quality of life of an individual during its last decades of life. Healthy aging is known as the ideal state in which we got to this stage, living it to the maximum possible degree of welfare. This concept has aroused great scientific interest in recent 50 years old. However, remarkably only at the mid 70 began to take hold the idea that society is useful for preserving the health of older people with good quality of life. In fact, in the last 10 healthy aging years has become a target at which point most of the efforts to prevent, treat and rehabilitate all kinds of diseases, neurological and psychiatric mainly.
