 Question: can you have a heart attack from laughing Context: The French brothers Joseph-Michel and Jacques-Étienne Montgolfier developed a hot air balloon in Annonay, Ardeche, France, and demonstrated it publicly on September 19, 1783, making an unmanned flight lasting 10 minutes. After experimenting with unmanned balloons and flights with animals, the first balloon flight with humans aboard, a tethered flight, performed on or around October 15, 1783, by Jean-Francois Pilatre de Rozier who made at least one tethered flight from the yard of the Reveillon workshop in the Faubourg Saint-Antoine. Later that same day, Pilatre de Rozier became the second human to ascend into the air, reaching an altitude of 26 m (85 ft), the length of the tether. The first free flight with human passengers was made a few weeks later, on November 21, 1783. King Louis XVI had originally decreed that condemned criminals would be the first pilots, but de Rozier, along with Marquis François d'Arlandes, petitioned successfully for the honor. The first military use of a hot air balloon happened in 1794 during the battle of Fleurus, when the French used the balloon l'Entreprenant for observation.

The tunnel connects end-to-end with the LGV Nord and High Speed 1 high-speed railway lines. In 2017 through rail services carried 10.3 million passengers and 1.22m tonnes of freight, and the Shuttle carried 10.4m passengers, 2.6m cars, 51000 coaches, and 1.6m lorries (equivalent to 21.3m tonnes of freight). This compares with 11.7 million passengers, 2.6 million lorries and 2.2 million cars through the Port of Dover.

It includes all the academic programs up to the level of a bachelor's degree. For example, in the United States, an entry level university student is known as an undergraduate, while students of higher degrees are known as graduates. In some other educational systems and subjects, undergraduate education is post-secondary education up to the level of a master's degree; this is the case for some science courses in Britain and some medicine courses in Europe.
 Question: is a high school student considered an undergraduate Context: Organizational conflict, or workplace conflict, is a state of discord caused by the actual or perceived opposition of needs, values and interests between people working together. Conflict takes many forms in organizations. There is the inevitable clash between formal authority and power and those individuals and groups affected. There are disputes over how revenues should be divided, how the work should be done, and how long and hard people should work. There are jurisdictional disagreements among individuals, departments, and between unions and management. There are subtler forms of conflict involving rivalries, jealousies, personality clashes, role definitions, and struggles for power and favor. There is also conflict within individuals -- between competing needs and demands -- to which individuals respond in different ways.
