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: National Money Mart Company, commonly known as Money Mart, is a Canadian financial services company that provides payday loans, cheque cashing, tax preparation and money transfer services to the underbanked. It was founded in Edmonton, Alberta in 1982, and by 2010 it had 412 stores across Canada with an additional 53 franchised stores. The head office is located in Victoria, BC.
 Question: are cash money and money mart the same company Context: Collard greens are a staple vegetable in Southern U.S. cuisine. They are often prepared with other similar green leaf vegetables, such as kale, turnip greens, spinach, and mustard greens in the dish called ``mixed greens''. Typical seasonings when cooking collards are smoked and salted meats (ham hocks, smoked turkey drumsticks, smoked turkey necks, pork neckbones, fatback or other fatty meat), diced onions, vinegar, salt, and black pepper, white pepper, or crushed red pepper, and some cooks add a small amount of sugar. Traditionally, collards are eaten on New Year's Day, along with black-eyed peas or field peas and cornbread, to ensure wealth in the coming year. Cornbread is used to soak up the ``pot liquor'', a nutrient-rich collard broth. Collard greens may also be thinly sliced and fermented to make a collard sauerkraut that is often cooked with flat dumplings.
 Question: are collard greens the same as mustard greens Context: Atomic radii vary in a predictable and explicable manner across the periodic table. For instance, the radii generally decrease along each period (row) of the table, from the alkali metals to the noble gases; and increase down each group (column). The radius increases sharply between the noble gas at the end of each period and the alkali metal at the beginning of the next period. These trends of the atomic radii (and of various other chemical and physical properties of the elements) can be explained by the electron shell theory of the atom; they provided important evidence for the development and confirmation of quantum theory. The atomic radii decrease across the Periodic Table because as the atomic number increases, the number of protons increases across the period, but the extra electrons are only added to the same quantum shell. Therefore, the effective nuclear charge towards the outermost electrons increases, drawing the outermost electrons closer. As a result, the electron cloud contracts and the atomic radius decrease.
 Question: is there a relationship between atomic number and atomic radii for elements in a single period Context: The cycloalkanes without side chains are classified as small (cyclopropane and cyclobutane), common (cyclopentane, cyclohexane, and cycloheptane), medium (cyclooctane through cyclotridecane), and large (all the rest). Each is an isomer of its alkene counterpart--for example, cyclopropane has the same chemical formula (CH) as propene.
