Data on individual, economic, social changes linked to dramatically aging population.  Rates of smoking and excessive alcohol consumption have declined among those 65 and older, but the percentage of overweight and obese people has increased. Between 2003-2006, 72 percent of older men and 67 percent of older women were overweight or obese. Obesity is associated in increased rates of diabetes, arthritis, and impaired mobility, and in some cases with higher death rates.
