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: 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.
 Question: are there more moves in go than atoms in the universe Context: The United States women's national soccer team (USWNT) represents the United States in international women's soccer. The team is the most successful in international women's soccer, winning three Women's World Cup titles (including the first ever Women's World Cup in 1991), four Olympic women's gold medals (including the first ever Olympic Women's soccer tournament in 1996), seven CONCACAF Gold Cup wins, and ten Algarve Cups. It medaled in every single World Cup and Olympic tournament in women's soccer history from 1991 to 2015, before being knocked out in the quarterfinal of the 2016 Summer Olympics. The team is governed by United States Soccer Federation and competes in CONCACAF (the Confederation of North, Central American and Caribbean Association Football).
 Question: have the us women's won a world cup Context: The number of valence electrons of an element can be determined by the periodic table group (vertical column) in which the element is categorized. With the exception of groups 3--12 (the transition metals), the units digit of the group number identifies how many valence electrons are associated with a neutral atom of an element listed under that particular column.
 Question: the number of valence electrons in an atom of an element is equal to the group number Context: Gerard Marenghi (born January 24, 1920), known as Jerry Maren, is an American actor and the last surviving Munchkin of the classic 1939 MGM film The Wizard of Oz, in which he portrayed a member of the Lollipop Guild. He became the last known survivor of the Munchkin cast (there may be some child actors who played Munchkins who also are still alive), following the death of fellow Munchkin Ruth Duccini on January 16, 2014.
