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 northern bobwhite, Virginia quail or (in its home range) bobwhite quail (Colinus virginianus) is a ground-dwelling bird native to the United States, Mexico, and the Caribbean. It is a member of the group of species known as New World quails (Odontophoridae). They were initially placed with the Old World quails in the pheasant family (Phasianidae), but are not particularly closely related. The name ``bobwhite'' derives from its characteristic whistling call. Despite its secretive nature, the northern bobwhite is one of the most familiar quails in eastern North America because it is frequently the only quail in its range. Habitat degradation has likely contributed to the northern bobwhite population in eastern North America declining by roughly 85% from 1966-2014. This population decline is apparently range-wide and continuing.
 Question: is a quail the same as a bobwhite Context: Canadian law requires that all persons entering Canada must carry proof of both citizenship and identity. A valid U.S. passport or passport card is preferred, although a birth certificate, naturalization certificate, citizenship certificate, or another document proving U.S. nationality, together with a government-issued photo ID (such as a driver's license) are acceptable to establish identity and nationality. However, the documents required to return to the United States can be more restrictive (for example, a birth certificate and photo ID are insufficient) -- see the section below on Return entry into the U.S.
 Question: can i use my certificate of naturalization to travel to canada Context: Since each location on the board can be either empty, black, or white, there are a total of 3 possible board positions on a square board with length n; however only part of them are legal. Tromp and Farnebäck derived a recursive formula for legal positions L ( m , n ) (\displaystyle L(m,n)) of a rectangle board with length m and n. The exact number of L ( 19 , 19 ) (\displaystyle L(19,19)) is obtained in 2016. They also find an asymptotic formula L ≈ A B m + n C m n (\displaystyle L\approx AB^(m+n)C^(mn)) , where A ≈ 0.8506399258457145 (\displaystyle A\approx 0.8506399258457145) , B ≈ 0.96553505933837387 (\displaystyle B\approx 0.96553505933837387) and C ≈ 2.975734192043357249381 (\displaystyle C\approx 2.975734192043357249381) . It has been estimated that the observable universe contains around 10 atoms, far fewer than the number of possible legal positions of regular board size (m=n=19). As the board gets larger, the percentage of the positions that are legal decreases.

They are native to Asia and northeastern Europe. Most species originate from East Asia and the center of diversity is in China. Countless horticultural varieties and cultivars exist.
