Pokedream, how wrong are you?
-It is true that life expectancy in the Middle Ages and earlier was low; however, many take this to mean that people usually died around the age of 30. In fact, the low life expectancy is an average based on high infant mortality, and the usual lifespan of adults was much higher. A 21-year-old man in medieval England, for example, could by one estimate expect to live to the age of 64.
-The United States Constitution was written on parchment, not hemp paper. However, drafts were likely written on hemp paper, as most paper at the time was made from hemp.
-The word "fuck" did not originate in Christianized Anglo-Saxon England (7th century CE) as an acronym for "Fornication Under Consent of King"; nor did it originate as an acronym for "For Unlawful Carnal Knowledge", either as a sign posted above adulterers in the stocks, or as a criminal charge against members of the British Armed Forces; nor did it originate during the 15th-century Battle of Agincourt as a corruption of "pluck yew" (an idiom falsely attributed to the English for drawing a longbow). Modern English was not spoken until the 16th century, and words such as "fornication" and "consent" did not exist in any form in English until the influence of Anglo-Norman in the late 12th century. The earliest recorded use of "fuck" in English comes from c. 1475, in the poem "Flen flyys", where it is spelled fuccant (conjugated as if a Latin verb meaning "they fuck"). It is of Proto-Germanic origin, and is related to either Dutch fokken and German ficken or Norwegian fukka.
-The word "crap" did not originate as a back-formation of British plumber Thomas Crapper's surname, nor does his name originate from the word "crap", although the surname may have helped popularize the word. The surname "Crapper" is a variant of "Cropper", which originally referred to someone who harvested crops. The word "crap" ultimately comes from Medieval Latin crappa, meaning "chaff".
-Meteorites are not necessarily hot when they reach the Earth. In fact, many meteorites are found with frost on them. As they enter the atmosphere, having been warmed only by the sun, meteors have a temperature below freezing. Frictional heating then melts a meteor's outside layer, but molten material is blown off and the interior does not have time to warm appreciably.
-Contrary to popular belief, dogs do not sweat by salivating. It is not true that dogs do not have sweat glands or have sweat glands only on their tongues. They do sweat, mainly through the footpads. However, dogs do primarily regulate their body temperature through panting.
-Glass is not a high-viscosity liquid at room temperature but an "amorphous solid" that only begins to flow above the glass transition temperature, though the exact nature of the glass transition is not considered settled among theorists and scientists. Panes of stained glass windows are often thicker at the bottom than at the top, and this has been cited as an example of the slow flow of glass over centuries. However, this unevenness is due to the window manufacturing processes used at the time. Normally the thick end of glass would be installed at the bottom of the frame, but it is also common to find old windows where the thicker end has been installed to the sides or the top.One researcher estimated in 1998 that for glass to actually "flow" at room temperatures would take many times the age of the earth.
-Although it is commonly believed that most body heat is lost through a person's head, heat loss through the head is not more significant than other parts of the body when naked. This may be a generalization of situations in which it is true, such as when the head is the only uncovered part of the body, or in infants, where the head is a significant fraction of body mass. Multiple studies have shown that for uncovered infants, lined hats significantly reduce heat loss and thermal stress.
-Humans have more than five senses. Although definitions vary, the actual number ranges from 9 to more than 20. In addition to sight, smell, taste, touch, and hearing, which were the senses identified by Aristotle, humans can sense balance and acceleration (equilibrioception), pain (nociception), body and limb position (proprioception or kinesthetic sense), and relative temperature (thermoception). Other senses sometimes identified are the sense of time, itching, pressure, hunger, thirst, fullness of the stomach, need to urinate, need to defecate, and blood carbon dioxide levels.
-Drinking normal levels of caffeinated beverages does not cause a net dehydration effect. The mild diuretic effect of caffeine is offset by the large amount of water in the caffeinated beverage.
