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: Typically, no license or advanced training beyond just firearm familiarization (for rentals) and range rules familiarization is usually required for using a shooting range in the United States; the only common requirement is that the shooter must be at least 18 or 21 years old (or have a legal guardian present), and must sign a waiver prior to shooting.
 Question: can you shoot a gun without a license Context: The coefficient of variation (CV) is defined as the ratio of the standard deviation σ (\displaystyle \ \sigma ) to the mean μ (\displaystyle \ \mu ) : c v = σ μ . (\displaystyle c_(\rm (v))=(\frac (\sigma )(\mu )).) It shows the extent of variability in relation to the mean of the population. The coefficient of variation should be computed only for data measured on a ratio scale, as these are the measurements that can only take non-negative values. The coefficient of variation may not have any meaning for data on an interval scale. For example, most temperature scales (e.g., Celsius, Fahrenheit etc.) are interval scales that can take both positive and negative values, whereas the Kelvin temperature can never be less than zero, which is the complete absence of thermal energy. Hence, the Kelvin scale is a ratio scale. While the standard deviation (SD) can be derived on both the Kelvin and the Celsius scale (with both leading to the same SDs), the CV is only relevant as a measure of relative variability for the Kelvin scale.
 Question: can coefficient of variation be more than 1 Context: The umbilical arteries supply deoxygenated blood from the fetus to the placenta. There are usually two umbilical arteries present together with one umbilical vein in the umbilical cord. The umbilical arteries surround the urinary bladder and then carry all the deoxygenated blood out of the fetus through the umbilical cord. Inside the placenta, the umbilical arteries connect with each other at a distance of approximately 5 mm from the cord insertion in what is called the Hyrtl anastomosis. Subsequently, they branch into chorionic arteries or intraplacental fetal arteries.
 Question: does the umbilical artery carry oxygenated blood to the conceptus Context: The city has four distinct seasons: a cold, snowy winter; a hot, dry summer; and two relatively wet transition periods. The climate of the Salt Lake City area is generally subhumid, not semi-arid as often claimed. Under the Köppen climate classification, Salt Lake City has a hot-summer humid continental climate (Dfa), with relatively drier summers than the rest of the year. The Pacific Ocean is the primary influence on the weather, contributing storms from about October to May, with spring being the wettest season. Snow falls frequently during the winter, contributed largely by the lake-effect from the Great Salt Lake. The only source of precipitation in the summer is monsoon moisture moving north from the Gulf of California. Summers are hot, frequently reaching above 100 °F (38 °C), while winters are cold and snowy. However, winters are warmer than one would expect at this elevation and latitude, due to the Rocky Mountains to the east and north that usually block powerful polar highs from affecting the state during the winter. Temperatures rarely fall below 0 °F (-18 °C), but frequently stay below freezing. Temperature inversions during winter can lead to thick overnight fog and daytime haze in the valley as cool air, moisture, and pollutants are trapped in the valley by surrounding mountains.
