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: A shoot-out is usually considered for statistical purposes to be separate from the match which preceded it. In the case of a two-legged fixture, the two matches are still considered either as two draws or as one win and one loss; in the case of a single match, it is still considered as a draw. This contrasts with a fixture won in extra time, where the score at the end of normal time is superseded. Converted shoot-out penalties are not considered as goals scored by a player for the purposes of their individual records, or for ``golden boot'' competitions.
 Question: do penalty shootout goals count for golden boot Context: A dingo--dog hybrid is a cross between a dingo and a domestic dog. The current population of free ranging domestic dogs in Australia is now probably higher than in the past. However, the proportion of the so-called ``pure'' dingoes (dogs with exclusively dingo-ancestry) has been on the decrease over the last few decades due to hybridisation and is regarded as further decreasing.
 Question: can you breed a dog with a dingo Context: For nearly all models of induction cooktops, a cooking vessel must be made of, or contain, a ferromagnetic metal such as cast iron or some stainless steels. However, copper, glass, non magnetic stainless steels, and aluminum vessels can be used if placed on a ferromagnetic disk which functions as a conventional hotplate.
 Question: can we use stainless steel in induction stove Context: A turn on red is a principle of law permitting vehicles at a traffic light showing a red signal to turn into the direction of traffic nearer to them (almost always after a complete stop) when the way is clear, without having to wait for a green signal. It is intended to allow traffic to resume moving, with minimal risk provided that proper caution is observed.
 Question: are you allowed to make a right turn on red Context: Carnitine (β-hydroxy-γ-N-trimethylaminobutyric acid, 3-hydroxy-4-N,N,N-trimethylaminobutyrate) is a quaternary ammonium compound involved in metabolism in most mammals, plants and some bacteria. Carnitine may exist in two isomers, labeled D-carnitine and L-carnitine, as they are optically active. At room temperature, pure carnitine is a white powder, and a water-soluble zwitterion with low toxicity. Carnitine only exists in animals as the L-enantiomer, and D-carnitine is toxic because it inhibits the activity of L-carnitine. Carnitine, derived from an amino acid, is found in nearly all organisms and animal tissue. Carnitine is the generic expression for a number of compounds that include L-carnitine, acetyl-L-carnitine, and propionyl-L-carnitine. It is most accumulated in cardiac and skeletal muscles as it accounts for 0.1% of its dry matter. It was first derived from meat extracts in 1905, therefore the name carnitine is derived from Latin ``carnus'' or flesh. The body synthesizes enough carnitine from lysine side chains to keep up with the needs of energy production in the body as carnitine acts as a transporter of long-chain fatty acids into the mitochondria to be oxidized and produce energy. Some individuals with genetic or medical disorders (like preterm infants) cannot make enough, so this makes carnitine a conditionally essential nutrient for them.
