Though it’s literally impossible to know everything there is to know in the universe, there are some fundamental things about being a human being in the modern world that everyone should strive to know. Core skills like cooking and cleaning allow you to be self-sufficient. Meanwhile, knowing how antibiotics work, why cat bites can be dangerous, and what chemicals to never ever mix together can actually end up saving your life.
Reddit users had a very informative discussion on r/NoStupidQuestions in a thread that went viral. They shared the pieces of ‘basic’ knowledge that everyone should know, but that a scary number of people may be oblivious about. Check out what they feel is vital to know in the 21st century as you keep scrolling.
Bored Panda got in touch with Glenn Geher, Ph.D., who was kind enough to shed some light on the evolutionary reasons why people might get embarrassed about not knowing something that others do. He also shared his thoughts on how to fill those knowledge gaps and whether it's easier to survive in the modern world than in the far past. Geher is a professor of psychology at the State University of New York at New Paltz and a published author, and you'll find our full interview with him as you read on.

Bored Panda wanted to get Professor Geher's thoughts on the evolutionary perspective behind embarrassment at one's knowledge gaps. 

"In so many ways part of the human social experience pertains to seeking some sort of status within a group," he said.

"If you're the one who does not know what others see as 'common knowledge,' this fact might not bear well for your social standing as you might not come off as that smart," Dr. Geher told us via email.

"For this reason, people are often hesitant to admit that they don't know something that everyone else seems to know."

We were also curious whether it's actually easier to survive in the 21st century compared to life a long time ago,, especially in developed countries. According to Dr. Geher, from the State University of New York at New Paltz, it's not as clear-cut as someone might think.

"In some ways, living is easier these days relative to our ancestral, nomadic past. For instance, searching for food nowadays often involves opening one's refrigerator as opposed to going out for a 6-hour hunt," he explained to Bored Panda.

"That said, many features of the modern world are sorely mismatched from ancestral conditions and for this reason, the modern 'conveniences' often come back to harm us. So we might be able to eat lots of cheap processed foods easily and cheaply, but this fact may come back to haunt us later in life in the form of a number of health problems such as Type-II diabetes."

The professor had some suggestions on how someone might go about filling in their knowledge gaps in the 21st century. "Learning about our evolved psychology and evolutionary past is often a good start. Understanding that humans evolved to live in small groups of familiar others under nomadic conditions can help us go a long way toward understanding the broader human experience," Professor Geher said.

"I often say that to succeed in the modern day, it is often best to try to simulate ancestral conditions as much as possible. So, for instance, if you live in a large city of hundreds of thousands of people, it would be wise to form some smaller social groups that better resemble the small nomadic groups that characterized human social organization for the lion's share of human evolutionary history."

Rags soaked with paint thinner, varnish, oil-based paint, polyurethane, and/or other volatile oils can actually spontaneously combust without any outside ignition source. The oils slowly release heat as they oxidize, and for example in a pile at the bottom of a garbage can, that heat can build enough to start smoldering and eventually ignite. I didn't know about this until a year or two ago, so don't feel dumb if you didn't know either.

It’s completely natural to have some knowledge gaps, even when it comes to ‘basic’ knowledge. Some people specialize in certain areas and can be completely ignorant in others. Meanwhile, other individuals might simply lack the education—or the time, money, and opportunities to plug those gaps. 

Whatever the case, many people tend to create the illusion that they’re very knowledgeable. However, if something happens where they’re forced to admit to others and themselves that they may not be as smart as they thought they were, the person might get incredibly embarrassed.

After all, it’s not a great feeling to realize that you were ignorant about something that seemingly ‘everyone’ around you already knew. What’s important to understand here is that you’re not alone in this. Sooner or later, everyone’s faced with facts they either didn’t know or had misinterpreted.

Salt will clean blood out of any fabric, even the whitest clothes or bedsheets.
Just put a little heap of salt over the bloodied fabric. If the blood is dry, wet it with a few drops of cold water then put the pile of salt. Leave it for an hour or so, wipe the bloody salt off, then wash with soap.
Edited to add that the water should be cold - see comments below about hot water setting the stain
Edit 2 for people who menstruate:
An early or particularly heavy visitor can lead to embarrassing situations sometimes, especially if (like me) you have woken up on a Japanese flag while sleeping over at someone else's house or at camp. Regular old table salt is something you can find basically anywhere you go, at any time of day or night, without arousing too many questions. You can pour a heap of salt on your stains (and put a few drops of cold water if the stain is already a bit dry), and it should be soaked up before too long. It will take the blood out of mattresses, sheets, and pajamas/underwear.

Different antibiotics work on different bacteria. You can’t take random antibiotics you’ve stocked up on at home and assume they will work for an infection.
Doctors make an educated guess on what antibiotic to give for an infection. This is based on the probability of the infection being caused by a specific bacteria; this knowledge comes from research on what organisms most frequently cause certain infections in certain individuals.

The best way to deal with embarrassing yourself in public, whether due to your lack of knowledge or anything else, is to embrace those somewhat uncomfortable feelings. As we’ve covered on Bored Panda before, the healthy way to react is to show mild embarrassment because it makes you seem more down to earth. Meanwhile pretending you didn’t make a mistake or getting angry about the whole situation is unhealthy and can turn your embarrassment about your (lack of) knowledge into deep-rooted shame.

The best way to deal with serious knowledge gaps is to carve out even a little bit of time every day to learn more about the topic. If it’s something that affects your career, schoolwork, or daily life, it only makes sense to make it a priority. However, it can be hard to do this if you’re working full time, have a family to take care of, and have a bunch of other responsibilities.

That’s why it’s important to focus on the idea that spending even just a little bit of time on something is better than none. Even 15 minutes of reading up on a subject you know nothing about is miles better than putting it off ‘until next week’ when you hope to have several free hours or feel more motivated.

Verywell Mind notes that it takes an average of 66 days to form a new habit. So incremental effort pays off, so long as you stay consistent. And though it really does help if you have the money for a proper education, it doesn’t mean that you can’t learn new things even if you’re struggling financially. 

There are countless free resources available on the internet. In the meantime, if you have a public library in your local area, then you’ve got access to countless books, teaching materials, and videos as well. There are also free online courses you can sign up to that can help you raise your confidence and improve your knowledge.
