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: In a 2015 study, Cary Stothart, Walter Boot, and Daniel Simons attempted to replicate and extend the findings from both Graham and Burke's 2011 study and Steven Most and colleague's 2000 study on Amazon Mechanical Turk using a sample of 515 participants that varied in age. In this study, participants were tasked with counting the number of times a number of white moving objects crossed the vertical midpoint of a display while ignoring a number of black moving objects. The unexpected object in this case was a gray cross that moved horizontally across the display at various distances from the vertical midpoint (this was manipulated between participants). Overall, they found that inattentional blindness susceptibility increases with age, which replicates the finding from Graham and Burke. In fact, they found that every 10 years of age was associated with a 1.3 fold increase in the probability of displaying inattentional blindness. They also found that the probability of inattentional blindness increases as the distance between the observer's focus of attention and the unexpected object increases, which replicates the finding from Most and colleagues. However, they also found that the relationship that age has with inattentional blindness does not change as a function of the unexpected object's distance from the focus of attention, suggesting that useful field of view does not mediate the relationship between age and inattentional blindness.
 Question: does age have any influence on attentional ability or inattentional blindness Context: Hair color is the pigmentation of hair follicles due to two types of melanin: eumelanin and pheomelanin. Generally, if more eumelanin is present, the color of the hair is darker; if less eumelanin is present, the hair is lighter. Levels of melanin can vary over time causing a person's hair color to change, and it is possible to have hair follicles of more than one color on the same person. Particular hair colors are associated with ethnic groups. Gray or white hair is associated with age.

It marks the unofficial start of the summer vacation season, while Labor Day marks its end.
 Question: is memorial day the last monday in may Context: Filming began in Shreveport, Louisiana, in mid-July 2012. Because Olympus Has Fallen was filmed so far from its actual setting of Washington, D.C., the entire production relied heavily upon visual effects, particularly computer-generated imagery. For example, computers were used to create nearly all of the opening sequence in which the First Lady is killed in a car accident, with chroma key greenscreen technology used to composite the actors into the computer-generated snowy scenery. For scenes where actors walked in or out of the White House, a first-floor façade and entrance were built; computers added the second floor, roof, and downtown D.C. cityscape. Action scenes with the White House in the background were filmed in open fields and the White House and D.C. were added in post-production.
