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: Cancer Treatment Centers of America (CTCA), headquartered in Boca Raton, Florida, is a national, for-profit network of five comprehensive cancer care and research centers and three out patient care centers that serves cancer patients throughout the United States. CTCA follows an integrative approach to cancer care that uses conventional approaches like surgery, chemotherapy, radiation and immunotherapy to treat the cancer, while also offering integrative therapies to help manage side effects like pain, nausea, fatigue, lymphedema, malnutrition, depression and anxiety.

It is the sixth installment in the Mission: Impossible film series, and the second film to be directed by McQuarrie after Rogue Nation (2015), making him the first person to direct more than one film in the franchise. The cast includes Tom Cruise, Ving Rhames, Simon Pegg, Rebecca Ferguson, Sean Harris, Michelle Monaghan and Alec Baldwin, all of whom reprise their roles from previous films, while Henry Cavill, Angela Bassett and Vanessa Kirby join the franchise. In the film, Ethan Hunt (Cruise) and his team must outrun a CIA agent (Cavill) tasked with killing them after a mission goes wrong.

 Question: does the ampulla of vater only contain pancreatic juice Context: Star vs. the Forces of Evil typically follows a format of two 11-minutes long independent ``segments'' per episode, with individual writing and directing credits for each, although it occasionally opts for a single, 22-minutes long story instead. The first episode aired on January 18, 2015 on Disney Channel as a special preview, becoming the most-watched animated series debut in Disney XD's history; the first season subsequently officially premiered on Disney XD on March 30, 2015. The third season started on July 15, 2017 and concluded on April 7, 2018. On February 28, 2017, the series was officially renewed for a fourth season. Nearly a year after the renewal, it was announced that the show would be moving to Disney Channel for its fourth season.
 Question: has star vs the forces of evil ended Context: According to the theory of relativity, no information can travel faster than the speed of light in vacuum, but this does not mean that the refractive index cannot be lower than 1. The refractive index measures the phase velocity of light, which does not carry information. The phase velocity is the speed at which the crests of the wave move and can be faster than the speed of light in vacuum, and thereby give a refractive index below 1. This can occur close to resonance frequencies, for absorbing media, in plasmas, and for X-rays. In the X-ray regime the refractive indices are lower than but very close to 1 (exceptions close to some resonance frequencies). As an example, water has a refractive index of 6999999999740000000♠0.99999974 = 1 − 6993260000000000000♠2.6×10 for X-ray radiation at a photon energy of 6985480652946099999♠30 keV (0.04 nm wavelength).
