Health care (or healthcare) is the diagnosis, treatment, and prevention of disease, illness, injury, and other physical and mental impairments in humans. Health care is delivered by practitioners in medicine, chiropractic, dentistry, nursing, pharmacy, allied health, and other care providers. It refers to the work done in providing primary care, secondary care and tertiary care, as well as in public health.

Access to health care varies across countries, groups and individuals, largely influenced by social and economic conditions as well as the health policies in place. Countries and jurisdictions have different policies and plans in relation to the personal and population-based health care goals within their societies. Health care systems are organizations established to meet the health needs of target populations. Their exact configuration varies from country to country. In some countries and jurisdictions, health care planning is distributed among market participants, whereas in others planning is made more centrally among governments or other coordinating bodies. In all cases, according to the World Health Organization (WHO), a well-functioning health care system requires a robust financing mechanism; a well-trained and adequately-paid workforce; reliable information on which to base decisions and policies; and well maintained facilities and logistics to deliver quality medicines and technologies.

Hannity dropped out of New York University and Adelphi University.

Hannity hosted his first talk radio show in 1989 at the volunteer college station at UC Santa Barbara, KCSB-FM, while working as a general contractor. The show aired for 40 hours of air time; Regarding his first show, Hannity has said, "I wasn't good at it. I was terrible." Hannity's weekly show on KCSB was canceled after less than a year by station managers. This was after two shows featuring the book The AIDS Coverup: The Real and Alarming Facts about AIDS by Gene Antonio; among other remarks made during the broadcast, Hannity told a lesbian caller "I feel sorry for your child". The station later reversed its decision to dismiss Hannity due in part to a campaign conducted by the Santa Barbara Chapter of the American Civil Liberties Union. Hannity decided against returning to KCSB.
