Found something that sent shivers down your spine just by looking at it yet? If not, continue scrolling and you just might; this list covers all sorts of aggravating things, showing just how easily annoyed some of us are.

For some people, all it takes is someone’s peculiar way of talking, or—my own personal nightmare—chewing so loud you can hear them at the other end of the room. But those around me might not understand what it is about the loud munching that drives me crazy, as it doesn’t bother them one bit. The reason why that is might be linked to something psychologists call ‘inattentional blindness’.

Insider pointed out that sometimes individuals get irritated because they notice something annoying; that one word the radio host keeps saying over and over, and over again, for example. It’s the instances when people don’t pay attention to such things as a word repeated one too many times that are called ‘inattentional blindness’.

Even though typically, when someone points out something annoying, it results in two people irritated by the same thing rather than both of them exhibiting inattentional blindness, such a seemingly aggravating state can actually be beneficial. Getting annoyed snaps us out of the stupor, consequently making us react to a situation, which can be dangerous. In a way, one unpleasant situation can help us avoid another unpleasant one.

Insider suggested that there are some universally annoying stimuli after all, such as the oh-so-lovely sound of nails meeting the chalkboard. However, even when the source of irritation is one and the same, the underlying reasons for such a negative feeling can differ greatly. According to the founder of the ‘A Place Of Hope’ center, author Dr. Gregory Jantz, reasons for an individual’s irritability can be categorized into three groups: physical, psychological, and other.

According to Dr. Jantz, physical reasons for feeling irritable typically relate to aches in our body, illnesses, hunger, sleep deprivation, and hormones. Psychological ones include stress and lack of healthy boundaries or emotional regulation skills. Into the ‘others’ category, the expert puts plausible links to anxiety, depression, borderline personality disorder, or sensory processing issues.

The mix of emotions that irritating situations often entail might seem tiresome to handle or simply not worth it. But former professor of counseling at St. Louis Community College at Florissant Valley, author, and expert in habit change, Meg Selig, suggests that one shouldn’t discount the sense of being annoyed at something, as it might indicate a certain problem.

In a piece for Psychology Today, she pointed out that getting easily irritated might illustrate the need to set a certain limit or protect your personal resources, such as time; it can also be linked to resentment, anger, or perfectionism, which should be acknowledged or resolved.

“We all get annoyed by different things, so it's important to recognize that a person is not necessarily inflicting psychological warfare on you through thoughtless actions,” Selig explained. “When your neighbor has been using his beloved leaf-blower for 45 minutes, it's irritating but not something to take personally.”

Some people don’t even need a leaf-blower to get on others’ nerves; and it can’t be hard to explain why. Well, researchers tried analyzing what it is about certain people that makes others want to leave the room the moment they enter. That’s how they coined the term ‘affective presence’, which measures how a person influences those around them—be it positively or in a way that drives individuals crazy.

Negative ‘affective presence’ can be part of why some humans annoy us; or it might simply be their lack of manners and other traits. A survey commissioned by Sky Mobile revealed that such impolite people are some of the most annoying things in modern society; in Britain, at least.

A study of roughly 2,000 adults found that the top five things Brits find the most annoying are people not listening to you, people pushing into a queue, people who don't say please or thank you, people who think that rules don't apply to them, and—no longer relating to people, yet still plenty annoying—splashing your favorite top or jeans with something. (Just going to add that people eating loudly or sloppily followed closely as number six.)

Annoyances of a modern day citizen undeniably differ from those of people of the past; and some of them are oddly specific. For example, the least annoying things on the list of the 40 gray hair-inducing matters are waiting too long for an online transaction to come out of your bank account, listening to kids arguing (alright, this might have been equally annoying ages ago), the fight to get your bag from baggage reclaim after a flight, being outbid on eBay, and “having to park on the wrong side of a petrol pump and reach the hose all the way around your car, rather than waiting for one on your side to become free”.

Some modern-day annoyances ought to be related to technology, and, well… they are. Statista revealed that when it comes to apps, for instance, it’s adverts that drive nearly 70% of users crazy; taking too long to load, having too many push notifications, or requesting login information in order to use the app also don’t play to its advantage.
