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: The Selective Service System is an independent agency of the United States government that maintains information on those potentially subject to military conscription. Virtually all male U.S. citizens and male immigrant non-citizens between the ages of 18 and 25 are required by law to have registered within 30 days of their 18th birthdays and must notify Selective Service within ten days of any changes to any of the information they provided on their registration cards, like a change of address. A 2010 Government Accountability Office report estimated the registration rate at 92% with the names and addresses of over 16.2 million men on file. However, the only audit of the addresses of registrants on file with the Selective Service System, in 1982, found that 20--40% of the addresses on file with the Selective Service System for registrants in the age groups that would be drafted first were already outdated, and up to 75% for those registrants in their last year of potential eligibility to be drafted would be invalid.
 Question: is it required to register for the selective service 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: Coronary artery disease (CAD), also known as ischemic heart disease (IHD), refers to a group of diseases which includes stable angina, unstable angina, myocardial infarction, and sudden cardiac death. It is within the group of cardiovascular diseases of which it is the most common type. A common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck, or jaw. Occasionally it may feel like heartburn. Usually symptoms occur with exercise or emotional stress, last less than a few minutes, and improve with rest. Shortness of breath may also occur and sometimes no symptoms are present. In many cases, the first sign is a heart attack. Other complications include heart failure or an abnormal heartbeat.
