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: Denailing is the extraction of the nails from the fingers and/or toes, either as a medical procedure to treat severe nail infections, or as a method of torture. The United Nations Istanbul Protocol describes nail removal and the insertion of objects such as wire under the nail as forms of torture. Removed nails are capable of growing back normally over several months if the nail matrix is left intact through surgical extraction. However, if the matrix is damaged by trauma, it can result in an overgrowth of tissue from the proximal nail fold, resulting in the formation of pterygium. Particularly, if the nail matrix is burnt by a heated instrument, subsequent growth may produce nails which are striped, thin, or broken into longitudinal segments.
 Question: if you pull a nail out does it grow back Context: It is important to note that mithridatism is not effective against all types of poison (immunity generally is only possible with biologically complex types which the immune system can respond to) and, depending on the toxin, the practice can lead to the lethal accumulation of a poison in the body. Results depend on how each poison is processed by the body, ie, on how the toxic compound is metabolized or passed out of the body. In some cases, it is possible to build up tolerance against specific non-biological poisons. For some poisons, this involves conditioning the liver to produce more of the particular enzymes that deal with these poisons (for example alcohol). Another mechanism involves conditioning the target tissues of the poisons. These methods do not work for all non-biological poisons. Exposure to certain toxic substances, such as hydrofluoric acid and heavy metals, is either lethal or has little to no effect, and thus cannot be used in this way at all. Arsenic is a notable exception with some people actually having a genetic adaptation granting them higher resistance which can be replicated with mithridatism. In addition, simple toxins that work through chemical processes that bypass the immune system cannot be dealt with (good example would be the variants of cyanide).
 Question: can you build up a resistance to cyanide Context: Upper respiratory tract infections (URTI) are illnesses caused by an acute infection which involves the upper respiratory tract including the nose, sinuses, pharynx or larynx. This commonly includes nasal obstruction, sore throat, tonsillitis, pharyngitis, laryngitis, sinusitis, otitis media, and the common cold. Most infections are viral in nature and in other instances the cause is bacterial. Upper respiratory tract infections can also be fungal or helminth in origin, but these are far less common.
 Question: is pharyngitis a symptom of upper respiratory infection Context: In January 2014, it was announced that Davidson would be returning to Days for a three-month story arc after having departed with the show in November 2013.
