Intermittent exotropia is a fairly common condition. Sensory exotropia occurs in the presence of poor vision. Infantile exotropia (sometimes called congenital exotropia) is seen during the first year of life, and is less common than essential exotropia which usually becomes apparent several years later.
History of Labor Day. Labor Day, the first Monday in September, is a creation of the labor movement and is dedicated to the social and economic achievements of American workers. It constitutes a yearly national tribute to the contributions workers have made to the strength, prosperity, and well-being of our country.
Â­For a lot of people, Labor Day means two things: a day off and the end of summer. But why is it called Labor Day? Labor Day is a day set aside to pay tribute to working men and women. It has been celebrated as a national holiday in the United States and Canada since 1894. Â­Â­Labor unions themselves celebrated the first labor days in the United States, although there's some speculation as to exactly who came up with the idea.
