 Question: can you have a heart attack from laughing Context: Field Marshal has been the highest rank in the British Army since 1736. A five-star rank with NATO code OF-10, it is equivalent to an Admiral of the Fleet in the Royal Navy or a Marshal of the Royal Air Force in the Royal Air Force (RAF). A Field Marshal's insignia consists of two crossed batons surrounded by yellow leaves below St Edward's Crown. Like Marshals of the RAF and Admirals of the Fleet, Field Marshals traditionally remain officers for life, though on half-pay when not in an appointment. The rank has been used sporadically throughout its history and was vacant during parts of the 18th and 19th centuries (when all former holders of the rank were deceased). After the Second World War, it became standard practice to appoint the Chief of the Imperial General Staff (later renamed Chief of the General Staff) to the rank on his last day in the post. Army officers occupying the post of Chief of the Defence Staff, the professional head of all the British Armed Forces, were usually promoted to the rank upon their appointment.

These states would found a new nation -- the United States of America. John Adams was a leader in pushing for independence, which was passed on July 2 with no opposing vote cast.

Management of these services has been progressively transferred to the distinct autonomous communities of Spain, while some continue to be operated by the National Institute of Health Management (Instituto Nacional de Gestión Sanitaria, INGESA), part of the Ministry of Health and Social Policy (which superseded the Ministry of Health and Consumer Affairs--Ministerio de Sanidad y Consumo--in 2009). The activity of these services is harmonized by the Interterritorial Council of the Spanish National Health Service (Consejo Interterritorial del Servicio Nacional de Salud de España, CISNS) in order to give cohesion to the system and to guarantee the rights of citizens throughout Spain.
