By 2030, the number of Americans aged 65 and older will more than double to 71 million, equaling about 20 percent of the U.S. population, noted the report. Of course, older Americans will not be the only aged around the globe. "We are aging — not just as individuals or communities but as a world. In 2006, almost 500 million people worldwide were 65 and older," according to a report entitled Why Population Aging Matters: A Global Perspective, which was presented earlier this month at the State Summit on Global Aging presented. By 2030, that total is projected to increase to one billion — one in every eight of the earth's inhabitants. Significantly, the most rapid increases in the 65+ population are occurring in developing countries, "which will see a jump of 140 percent by 2030," reports Senior Journal.

The health of the age group coming up behind the 65+ people may also be questionable.

Beth Soldo, a University of Pennsylvania sociologist, and her colleagues studied data from the U.S. Health and Retirement Study and found that people in "their early to mid-50s were reporting more health problems than people that age had described previously," writes Gary Rotstein at The Pittsburgh Post-Gazette. This deserves to be taken with some skepticism, however, because "the federal data are not correlated with any actual health evaluations." A health care provider would refer to these "evaluations" as scientifically valid observations.

One possibility for the higher reporting of poor health may result from more stress and obesity. Or baby boomers may have higher definition of what constitutes good health. Also, more awareness of effective treatments and medications may lead people to feel less inclined to report their health as good.

Kenneth Manton, research professor at Duke University, said he "sees no basis for such fears and nothing in Soldo's study to change his mind," the article quotes Manton as having said.

Older Americans can minimize this cost, though, if improving and preserving older adults' health is more actively addressed, according to an updated report from the Centers for Disease Control and Prevention (CDC) and the Merck Co. Foundation. The CDC report presents information and recommendations to help older Americans live not just longer but better lives.

Three preventable behaviors — smoking, poor diet and physical inactivity — were the root causes of almost 35 percent of U.S. deaths in 2000. These behaviors represent risk factors that often lead to society's leading chronic killers: heart disease, cancer, stroke and diabetes. The report indicates that if people can live healthier and go to regular screenings, they can reduce the risk for many chronic diseases and help lower heath care costs.

The challenge is to better apply (i.e., more broadly) what we already know about helping to ensure that added years are healthy years, according to the report.

A closer look at some resources for helping older adults reduce the risk factors can help us all. For many people, physical inactivity may be the hardest challenge. The CDC provides quite a bit of resourceful information to generate motivation and become active.

If older adults take the advice provided by the health care provider community, and motivate themselves, they can achieve two goals: live healthier and perhaps longer, and reduce health care costs.
