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: Bok choy, pak choi or pok choi (Chinese: 上海青; pinyin: Shànghǎi qīng; literally: ``Shanghai Green''; Brassica rapa subsp. chinensis) is a type of Chinese cabbage. Chinensis varieties do not form heads and have smooth, dark green leaf blades instead, forming a cluster reminiscent of mustard greens or celery. Chinensis varieties are popular in southern China and Southeast Asia. Being winter-hardy, they are increasingly grown in Northern Europe. This group was originally classified as its own species under the name Brassica chinensis by Linnaeus.
 Question: is bok choy the same as pak choi Context: As an independent production, the film was picked up for distribution by Fox Searchlight Pictures and premiered at the 25th Sundance Film Festival. It garnered favorable reviews and became a successful ``sleeper hit'', earning over $60 million in worldwide returns, far exceeding its $7.5 million budget. Many critics lauded the film as one of the best from 2009 and drew comparisons to other acclaimed films such as Annie Hall (1977) and High Fidelity (2000).
 Question: is 500 days of summer an indie movie 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.
