Context: Death from laughter is a rare form of death, usually resulting from cardiac arrest or asphyxiation, caused by a fit of laughter. Instances of death by laughter have been recorded from the times of ancient Greece to the modern day.
 Question: can you have a heart attack from laughing Context: The WHMU also oversees the mobile medical suite aboard Air Force One and Air Force Two. Air Force One contains a full surgical suite with operating table, two beds, resuscitation equipment, various medical monitors, and a full pharmacy. Air Force Two contains a first aid unit as well as an automated external defibrillator, oxygen tanks, and limited pharmaceuticals. The WHMU also establishes temporary emergency medical facilities as needed to support presidential or vice presidential trips. These usually consist of an eight-member intensive care and surgical team, and a temporary operating room at each stop. WHMU staff may also carry operating room equipment in backpacks to provide emergency medical care as needed on-site when the temporary operating room is too distant. When the President travels overseas, an advance medical team travel ahead of Air Force One to set up its medical facilities days in advance. This way, a fully rested medical team is available to assist the President upon arrival and take over from the team which traveled aboard the presidential aircraft.

An alpha particle is identical to the nucleus of a helium-4 atom, which consists of two protons and two neutrons. It has a charge of +2e and a mass of 4u. For example, uranium-238 decays to form thorium-234. Alpha particles have a charge +2, but as a nuclear equation describes a nuclear reaction without considering the electrons -- a convention that does not imply that the nuclei necessarily occur in neutral atoms -- the charge is not usually shown.
 Question: is alpha emission the same as alpha decay Context: Saline water (more commonly known as salt water) is water that contains a significant concentration of dissolved salts (mainly NaCl). The salt concentration is usually expressed in parts per thousand (permille, ‰) or parts per million (ppm). The United States Geological Survey classifies saline water in three salinity categories. Salt concentration in slightly saline water is around 1,000 to 3,000 ppm (0.1--0.3%), in moderately saline water 3,000 to 10,000 ppm (0.3--1%) and in highly saline water 10,000 to 35,000 ppm (1--3.5%). Seawater has a salinity of roughly 35,000 ppm, equivalent to 35 grams of salt per one liter (or kilogram) of water. The saturation level is dependent on the temperature of the water. At 20 °C one milliliter of water can dissolve about 0.357 grams of salt; a concentration of 26.3%. At boiling (100 °C) the amount that can be dissolved in one milliliter of water increases to about 0.391 grams or 28.1% saline solution.
