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: After the caterpillar becomes a butterfly, the toxins shift to different parts of the body. Since many birds attack the wings of the butterfly, having three times the cardiac glycosides in the wings leaves predators with a very foul taste and may prevent them from ever ingesting the body of the butterfly. In order to combat predators that remove the wings only to ingest the abdomen, monarchs keep the most potent cardiac glycosides in their abdomens.
 Question: is there such thing as a poisonous butterfly Context: Although it is widely believed that a worker honey bee can sting only once, this is a partial misconception: although the stinger is in fact barbed so that it lodges in the victim's skin, tearing loose from the bee's abdomen and leading to its death in minutes, this only happens if the skin of the victim is sufficiently thick, such as a mammal's. Honey bees are the only hymenoptera with a strongly barbed sting, though yellow jackets and some other wasps have small barbs.
 Question: does a honey bee die after it stings you Context: Second-generation antihistamines cross the blood--brain barrier to a much lower degree than the first-generation antihistamines. Their main benefit is they primarily affect peripheral histamine receptors and therefore are less sedating. However, high doses can still induce drowsiness through acting on the central nervous system. Some second-generation antihistamines, notably cetirizine, can interact with CNS psychoactive drugs such as bupropion and benzodiazepines.
 Question: do second generation antihistamines cross the blood brain barrier Context: A passing lane is commonly referred to as a ``fast lane'' because it is often used for extended periods of time for through traffic or fast traffic. In theory, a passing lane should be used only for passing, thus allowing, even on a road with only two lanes in each direction, motorists to travel at their own pace.
 Question: is there a such thing as a fast lane Context: Arm span or reach (sometimes referred to as wingspan) is the physical measurement of the length from one end of an individual's arms (measured at the fingertips) to the other when raised parallel to the ground at shoulder height at a 90° angle. The average reach correlates to the person's height. Age and sex have to be taken into account to best predict height from arm span.
 Question: is the arm span the same as height Context: SAE is an extraterritorial (ET) variety of English, or a language variety that has been ``transported'' outside its mainland home. More specifically, SAE is a Southern hemisphere ET originating from later English colonisation in the 18th and 19th centuries (Zimbabwean, Australian, and New Zealand English are also Southern hemisphere ET varieties). SAE resembles British English more closely than it does American English due to the close ties that South African colonies maintained with the mainland in the 19th and 20th centuries. However, with the increasing influence of American pop-culture around the world via modes of contact like television, American English has become more familiar in South Africa. Indeed, some American lexical items are becoming alternatives to comparable British terms.
