As we move further into the 21st century, people are living longer than their ancestors. According to the Administration on Aging (a division of the Department of Health and Human Services), North Americans reaching age 65 have an average life expectancy of an additional 18.8 years (20.0 years for females and 17.3 years for males). In comparison, the average life expectancy for Americans in 1960 was 73 years. As the aging population grows, the medical community becomes more involved in the science of aging and more adept at treating and helping to prevent various conditions. As I've always maintained - it's not about anti-aging, rather optimal-aging. Let's work with our bodies and optimize the capability to live as long with as high quality of living as possible.
