Can We Prevent Aging?
People are living longer. In 1970, the average life expectancy at birth in the United States was 70.8 years; in 2008, it was 78.0 years; and by 2020, the U.S. Census Bureau projects life expectancy will reach 79.5 years.
Views on aging are also changing. Disease and disability were once considered an inevitable part of growing older, but that is no longer true. While aging does put us at greater risk for health issues, many older adults can be healthy and active well into their advancing years.
