American football is played almost exclusively in the autumn months; at the high school level, seasons run from late August through early November, with some playoff games and holiday rivalry contests being played as late as Thanksgiving. In many American states, the championship games take place in early December. College footballs regular season runs from September through November, while the main professional circuit, the National Football League, plays from September through to early January. Summer sports, such as association football (in Northern America, East Asia, Argentina, and South Africa), Canadian football, stock car racing, tennis, golf, cricket, and professional baseball, wrap up their seasons in early to late autumn; Major League Baseballs championship World Series is popularly known as the "Fall Classic". (Amateur baseball is usually finished by August.) Likewise, professional winter sports, such as ice hockey and basketball, and most leagues of association football in Europe, are in the early stages of their seasons during autumn; American college basketball and college ice hockey play teams outside their athletic conferences during the late autumn before their in-conference schedules begin in winter. The Christian religious holidays of All Saints Day and All Souls Day are observed in autumn in the Northern hemisphere. Easter falls in autumn in the southern hemisphere. The secular celebration of International Workers Day also falls in autumn in the southern hemisphere.
Signs and symptoms
Mild or early cases of Pagets are asymptomatic, and so most people are diagnosed with Pagets disease incidentally during medical evaluation for another problem. Approximately 35% of patients with Pagets have symptoms related to the disease when they are first diagnosed. Overall, the most common symptom is bone pain. When symptoms do occur, they may be confused with those of arthritis or other disorders, and so diagnosis may be delayed. Pagets may first be noticed as an increasing deformity of a persons bones.Pagets disease affecting the skull may cause frontal bossing, increased hat size, and headaches. Often patients may develop loss of hearing in one or both ears due to auditory foramen narrowing and resultant compression of the nerves in the inner ear. Rarely, skull involvement may lead to compression of the nerves that supply the eye, leading to vision loss. Associated conditions
Pagets disease is a frequent component of multisystem proteinopathy. Advanced Pagets disease may lead to other medical conditions, including:

Osteoarthritis may result from changes in bone shape that alter normal skeletal mechanics. For example, bowing of a femur affected by Pagets may distort overall leg alignment, subjecting the knee to abnormal mechanical forces and accelerating degenerative wear. Heart failure is a rare, reported consequence of severe Pagets disease (i.e. more than 40% skeletal involvement). The abnormal bone formation is associated with recruitment of abnormal blood vessels, forcing the cardiovascular system to work harder (pump more blood) to ensure adequate circulation. Kidney stones are somewhat more common in patients with Pagets disease.
