From the Document: "Long-term services and supports (LTSS) refers to a broad range of health and health-related services and other types of assistance that are needed by individuals over an extended period of time. The need for LTSS affects persons of all ages and is generally measured by limitations in an individual's ability to perform daily personal care activities such as eating, bathing, or dressing. The probability of needing LTSS increases with age. As the nation's population aged 65 and older continues to increase in size, and individuals continue to live longer post-retirement, the demand for LTSS is also expected to increase. In addition, advances in medical and supportive care may allow younger persons with disabilities to live longer."
