Federal health officials recently reported that Americans are living longer than ever and that life expectancy is increasing every year. People born in 2009 can expect to live 78.5 years thanks to better treatment of cardiovascular disease says the U.S. Centers for Disease Control and Prevention. The report also revealed that life expectancy has risen across gender and race for the last 50 years. But one expert said there are “some dark clouds swirling around the silver lining of data.” A recent analysis by the Institute of Medicine suggests that this increase in life span is not matched by an increase in “health span”—the time living in good health. A long life could mean a long time living with illness and disease so the next chapter in medical advance according to experts is to focus on lifestyle as much as medicine.
