Government officials estimate that almost 70 percent of Americans will require the use of long-term care at some point in their lives, but new findings suggest that many of them are not doing the things they need to ensure they get the care they need should any health issues arise, according to The Associated Press.

The poll, conducted by the AP-NORC Center for Public Affairs Research, found that two-thirds of adults 40 and older have done little to no planning for long-term care. There are a number of reasons for the alarming statistics, but experts believe one of the biggest is that people don’t believe they will never need the make use of such services, and if they do their family will be the ones to care for them.

”The expectation that your family is going to be there when you need them often doesn’t mean they understand the full extent of what the job of caregiving will be,” Susan Reinhard, the director of AARP’s Public Policy Institute, told the AP.

It’s important for older adults to think about their future healthcare decisions, even if they’re currently in good health. According to Census estimates, seniors will make up about 19 percent of the total U.S. population by 2030.
