âDog tagsâ is the informal term for the identification tags worn by military personnel, because of their resemblance to actual dog tags. The tags are primarily used for the identification of dead and wounded soldiers, and to convey essential basic medical information, such as blood type and history of inoculations, along with religious preference.
Medicare is a federal health insurance program while Medicaid is a federal-state medical assistance program. Medicare is an insurance program that provides medical care to people over 65. Seniors' medical bills are paid from funds which those covered have paid into. People of 65 are covered, regardless of their income...but it is not free.
Medicare and Medicaid are very different. Medicaid is a federal program for low-income, financially needy people, set up by the federal government and administered differently in each state. (This program is called Medi-Cal in California.).
