Life has progressed to the point where the battle for survival is rather at an intellectual level, no more at a physical one. Societies of our present are designed with everything needed in order to provide us with basic life conditions. We don’t hunt anymore, we have roofs over our hands, food is good and somewhat healthy, we don’t need to struggle as much for survival as our ancestors did. Furthermore, we do everything that is needed in order to keep our youth for longer. And it seems that people are indeed living longer but new data suggests that these longer years are marked by great illness.
Cognitive disorders are becoming increasingly popular among the elders, cancer is everywhere in all shapes and sizes, diabetes, heart problems and many more, most of them related to a chaotic lifestyle.
Most of the people who reach old age live sicker for longer, according to a study of all major diseases and injuries in 188 countries. On the other hand, general health has improved worldwide, thanks to enormous progress against infectious diseases, such as AIDS and malaria, in the past decade. General health also gains in fighting maternal and child illnesses.
Life expectancy has increased in length but not in health. People live more years with illness and disability.
A new study suggests that global life expectancy at birth for both sexes rose by 6.2 years, from 65.3 in 1990 to 71.3 in 2013. Healthy life expectancy at birth has rose by 5.4 years, from 56,9 in 1990 to 62,3 in 2013. Healthy life expectancy takes into account both mortality and the impact of non-fatal conditions and chronic diseases such as lung and heart disease, serious injuries and diabetes. All these damage the quality of life and imply heavy expenses and resource burdens.
For almost all the 188 countries studied, changes in healthy life expectancy between 1990 and 2013 were “positive and significant”, as the researchers have declared. At the same time, in some of the countries studied, such as Syria, Belize and Botswana, healthy life expectancy in 2013 was not significantly higher, compared to 1990.
The average life expectancy among individuals across the globe has improved by 6 years since 1990. Life expectancy has also improved by more than 5 years in the same time frame. Income and education have a deep impact on life expectancy levels but they are far from telling the whole truth. High income and education most of the times mean high levels of stress and sometimes high pressure leads to cancer and cognitive disorders.
