 Question: can you have a heart attack from laughing Context: A soccer-specific stadium typically has amenities, dimensions and scale suitable for soccer in North America, including a scoreboard, video screen, luxury suites and possibly a roof. The field dimensions are within the range found optimal by FIFA: 110--120 yards (100--110 m) long by 70--80 yards (64--73 m) wide. These soccer field dimensions are wider than the regulation American football field width of 53 ⁄ yards (48.8 m), or the 65-yard (59 m) width of a Canadian football field. The playing surface typically consists of grass as opposed to artificial turf, as the latter is generally disfavored for soccer matches since players are more susceptible to injuries. However, some soccer specific stadiums, such as Portland's Providence Park and Creighton University's Morrison Stadium, do have artificial turf.

 Question: is demarcus ware still playing in the nfl Context: In baseball, a pitcher can commit a number of illegal motions or actions that constitute a balk. Most of these violations involve a pitcher pretending to pitch when he has no intention of doing so. In games played under the Official Baseball Rules that govern all professional play in the United States and Canada, a balk results in a dead ball or delayed dead ball. In certain other circumstances, a balk may be wholly or partially disregarded. Under other rule sets, notably in the United States under the National Federation of High Schools (Fed or Federation) Baseball Rules, a balk results in an immediate dead ball. In the event a balk is enforced, the pitch is generally (but not always) nullified, each runner is awarded one base, and the batter (generally) remains at bat, and with the previous count. The balk rule in Major League Baseball was introduced in 1898.
