what are the nosebleeds seats

The term "nosebleed seats" refers to the seats in a public area, usually an athletic stadium or gymnasium, that are highest and farthest from the desired activity. These seats are so high and far away from the stage that you get a "nosebleed" from the high altitude. They are usually cheaper and have a poorer view than other seats. 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 during that years Army-Navy American football game. The nickname is in reference to the high elevation of the upper bowl from the field and the fact that people often get nosebleeds from the higher elevation. The higher you go above sea level, the thinner the air gets, causing nosebleeds. The term is also used in a tongue-in-cheek manner to refer to the upper tiers of a stadium.
