Nosebleed tickets or seats are the seats of a public area, usually an athletic stadium or gymnasium, that are highest and usually farthest from the desired activity. The term "nosebleed" refers jocularly to the effects of extremely high altitudes on the body, which can often cause nasal hemorrhaging, among other symptoms. The nosebleed section consists of seats that cost the least because they are far away from the action. The term appeared in print as early as 1953 when it was used to describe the last row in the end zone at Philadelphias Municipal Stadium (later John F. Kennedy Stadium) during that years Army-Navy American football game. The term is also used in music concerts to refer to the front row, where people are so tightly packed that they will get a nosebleed every time someone jostles past them to get a better position.
