As you scroll through the list, you might realize that you have seen people do these exact same things, and it might have even frustrated you. Let's look closely at some of the things that adults do in their 30s, which shows how irresponsible or cringe-worthy they can be.

For instance, one user mentioned how some people share all their business and drama on social media. Research says that a psychological factor that contributes to oversharing is narcissism. It stresses that individuals with narcissistic tendencies may feel an insatiable desire for attention and admiration and seek to fulfill it by sharing personal achievements, experiences, or even hardships on a public platform.

Other netizens mentioned things related to money and how adults do stupid things like buying expensive things or getting a pet they can't look after. Studies show that American household debt hit a record $16.9 trillion at the end of 2022, up $2.75 trillion since 2019. However, despite this staggering debt, folks still keep spending on unnecessary things and getting things that they can't really afford.

According to Investopedia, "People buy luxury goods despite not being able to afford them for several reasons, including a sense of irrationality, a belief that a higher price equals higher quality, a desire for higher self-esteem, and a desire for a sense of accomplishment." This just shows how consumerism has deep psychological underpinnings where people lack a sense of what's actually necessary.

Someone also mentioned how, despite getting old, people still stick with their unhealthy lifestyles, like eating fast food daily, getting extremely drunk every night, or having no proper sleep cycle. Time and again, research has stressed that a healthy lifestyle can not only help you feel better, but it can also reduce the risk of some diseases, lengthen your lifespan, save you money, and benefit the environment.

However, despite the warnings of experts, not everyone prioritizes their health as they actually should. In fact, studies have revealed the shocking truth that less than 3% of Americans have a healthy lifestyle. This just goes to show that there are very few people who are conscious about the kind of life they are living.

Some people also talked about how people refuse to mature with age, act childish, rely on others for everything, and never grow or learn anything from life. When some adults continue to cling to the carefree days of youth and find emotional and financial responsibilities challenging well into adulthood, it's called a Peter Pan syndrome.

Experts say that there are certain complex factors that can cause this syndrome like childhood experiences or economic factors. Although it’s more common in men, anyone can develop the behaviors associated with the syndrome. When someone realizes that they are suffering through it, it's always better to have it treated, isn't it?

If you are in your 30s and live in the developed world and do not have poverty or disability as a factor... You should know how to use household appliances (Washer, Dryer, Dishwasher, Stove) If you do not have any clue how to use a clothes washer - or figure it out on your own (especially with the instructions on the lid like in the olden days) - I don't have the patience to teach you. Regardless of gender full-stop: if you are a guy and don't know how to wash clothes because "that is woman's work" then... Jesus I have to get out of West Virginia!
