Aging – Understanding the Process
Less than one hundred years ago, the life expectancy of a male was only 48 years and a female was 50 years. Because of the incredible advances in medicine and the improvement in living conditions, this life expectancy has increased to well into the seventies for both genders.Many of the diseases that claimed the lives of children and young adults in past decades have now been virtually eradicated because of the mass immunization programs mounted by the public health sector. This, along with better housing and sanitation has led to a huge increase in the number of people living well into old age. Thus, there has been a great expansion in the need for geriatric care to alleviate the disease and disability attributed largely to old age.
