The United States population is older than it has ever been. Today, the country's median age is 38.9, which is nearly a decade older than it was in 1980. And the number of adults older than 65 is expected to balloon from 58 million to 82 million by 2050. The challenge of caring for the elderly, amid shortages of care workers, rising health care costs, and evolving family structures, is an increasingly urgent societal issue.
