1775: Things You Learn

2016-12-22T13:32:35Z

Tamarack: added citation for the fact that >70% of US children aged 5 to 14 learn to ride a bike

{{comic

| title = Things You Learn
| image = things_you_learn.png
| titletext = Guess who has two thumbs and spent the night in an ER after trying to rescue a kitten that ran under his car at a stoplight and climbed up into the engine compartment? And, thanks to antibiotics, will continue having two thumbs? THIS GUY. (P.S. kitten is safe!)
}}

==Explanation==
{{incomplete|Title text, fill table.}}
This graph shows various items of information plotted by two criteria: a horizontal "How Bad Is It If You Don't Know [THING]" axis and a vertical "How Easy It Is To Grow Up Without Learning [THING]" axis. Specifically, the vertical axis measures roughly how often you will run into problems if you are ignorant of the knowledge listed on the plot point. The horizontal axis measures how serious those problems are if they happen at all.

The title text describes an encounter Randall had the night before writing this comic where a cat climbed into the engine compartment of his car. (This comic was posted several hours late, possibly due to this very encounter.) It probably serves as an explanation for the seemingly out of place point on the graph about how serious cat bites are. The "two thumbs" is a reference to a well known type of jokes among English speakers. One of the most frequent forms is one person interrupting another mid-speech and asking "what has two thumbs and doesn't give a f*ck? THIS GUY!", before pointing to themselves with their thumbs. The idea is that you only direct the attention to your thumbs so that they can point back to you, though mentioning the thumbs was not actually required except as a topic change. Randall plays on an invertion of this joke as he might not have been able to make it at all without the intervention of the ER people. So here the "who has two thumbs", is not a deceiving distraction out of a boring conversation, and the thumbs are actually the focus of the phrase.

{| class="wikitable sortable"
! Ignorance is Bad !! Ignorance is Easy !! Information !! Comments
|-
| not bad || (very, very) easy || 100 digits of {{w|pi}} || Most people don't know more than a few digits of pi, and don't need to.
|-
| not bad || (very) easy || Lyrics to "{{w|We Didn't Start the Fire}}" || "We Didn't Start the Fire" is a 1989 hit song by Billy Joel. Its lyrics include brief, rapid-fire allusions to more than 100 headline events between 1949, the year of Joel's birth, and 1989. While the chorus is memorable, the verses of the song are just a list of people, events and random things from popular culture. The average person is somewhat more likely to know the lyrics to Billy Joel's 1989 hit song than 100 digits of pi, but not knowing them doesn't really have any serious consequences.
|-
| (very) bad || (very) easy || That cat bites are really serious and if bitten you need to wash the bite and call a doctor immediately || Most people assume that a cat bite is just a minor injury. In fact, it carries a fairly high risk of infection, which can be dangerous if not treated (by cleaning the bite to reduce the risk, and having a doctor examine the bite victim and apply additional treatments such as antibiotics if needed). At the same time, cat bites are quite rare, as cats default to their claws rather than their teeth when they need to attack something.
|-
| (very) bad || (very) easy || The red flags for an abusive relationship || It is fairly easy for someone to fall into a pattern of accepting abuse (particularly if the abuser is skilled at emotional manipulation) without realizing it, and the consequences can be mentally and physically devastating.
|-
| (very, very) bad || easy || The {{w|Stroke#Signs_and_symptoms|signs of a stroke}} || The symptoms of a {{w|stroke}} are somewhat variable, including facial drooping, arm weakness and slurred speech, depending on what areas of the brain are affected, and can be mistaken for other conditions. Identifying a stroke quickly and seeking treatment can make the difference between life and death, or between full recovery and permanent impairment.
|-
| bad || easy || Cough into your elbow, not your hand || Covering a cough with the inside of your elbow helps prevent spreading airborne germs and is generally recommended by medical organisations. Coughing into your hand deposits them onto your hand, where they are much more likely to be spread to another person (via handshake, food preparation, shared objects, etc)
|-
| not (too) bad || hard || How to ride a bike || Most children, especially in the United States[http://www.peopleforbikes.org/statistics/category/participation-statistics#youth], learn to ride a bike at a fairly young age. While this is a useful skill to know for both entertainment and transportation, it would generally not be terrible to not learn this skill.
|-
| not bad (at all) || hard || How to escape movie {{w|quicksand}} || Quicksand in movies is a common trope, and while its physics often differ from real quicksand, escaping from it is commonly done using similar methods (eg, not struggling, which increases the quicksand's viscosity). Knowing how to escape from quicksand is important if you sink into it, which is a situation most people are very unlikely to encounter.
|-
| not bad (at all) || (very) hard || Lyrics to "{{w|The Twelve Days of Christmas (song)|12 Days of Christmas}}" || Hearing the same Christmas songs over and over each year makes it hard not to learn the lyrics over time. However, the consequences of not doing so are minimal; at most, ignorance of popular culture may leave your friends [[1769|a bit surprised and dismayed]].
|-
| not bad (at all) || (very, very) hard || {{w|Theme music|TV theme songs}} || Most children in developed countries grow up watching at least some television. Many of these television shows play the same theme song before the show starts, and many of these have catchy lyrics. Therefore, by repetition, most children will learn at least one of these growing up, and often many.
|-
| bad || hard || That you have to empty the dryer lint trap || A {{w|clothes dryer}} resembles a washing machine, it uses hot air to heat the clothes so that the water evaporates more quickly.

The dryer's air exhaust and air filter are getting gradually covered with lint (= a kind of dust composed mainly of fiber) and must be cleaned regularly. Failing to remove the lint can cause the dryer to stop working effectively, introduce lint back onto your clothes, or (in extreme cases) start a fire.
|-
| (very) bad || (very) hard || {{w|Stop, drop and roll}} || This is a technique to extinguish a fire on one's own clothing, and is frequently taught to children for safety. Not knowing it (or forgetting it in a panic when the situation arises) can result in severe burns that could have been avoided by following the recommendation.
|-
| (very) bad || (very) hard || That you have to pay taxes || Most residents of most countries are legally obligated to pay taxes to their government. Penalties for not doing so often include large fines, and possibly prison sentences. Fortunately, it is something that children hear about quite a bit so it is very difficult to grow up without learning that it must be done.

1759: British Map

Tamarack: /* Transcript */ added transcript (first draft of text)

{{comic

==Explanation==
{{incomplete|Started the table, editing it now.}}

Many areas of the UK are most familiar to foreigners thanks to their depiction in various fantasy novels and TV series. This map labels some of these, as well as including many silly names that simply sound like real British towns to an American ear. A protractor is shown off the coast of the {{w|Mull of Kintyre}} in reference to the "{{w|Mull of Kintyre test}}" - the angle of the Mull defines the maximum allowed erectness for a man on British television.
