Contrary to a common misconception, fear isn't something we're born with, it's something we develop over time. In fact, babies don't exhibit it for the first time until they're around 8 to 12 months of age.
That means that most of our fears are learned at some point in our lives, and they're not all learned in the same way. Some fears, as psychologist Dr. Vanessa LoBue points out, can be learned by conditioning, or by having a negative experience with something. For instance, you might learn to be afraid of dogs if you’ve been bitten by a dog, or you might learn to be afraid of bees after getting stung. But we can also develop the jitters to things by watching someone else's fearful reaction. For example, instead of growing to be afraid of dogs by being bitten, we can also develop a fear of dogs by watching a friend freak out at the sight of a snarling Chihuahua. Likewise, we can learn to be afraid of dogs by hearing negative information as well, like hearing from your mom that little dogs bite.
So Reddit user Mahouswen decided to investigate this further and asked people on the platform to share what they find horrific in adulthood that didn't even bother them in childhood.

That your parents don't know everything and were making up it as they went because now I have kids and I don't know s**t and am making it up as I go.

As a kid, I didn’t realize you could seriously injure your back by simply sneezing.

Thunderstorms became scary once I owned a home near trees. Loved them as a kid.

They give nearly everyone a car license. We all just trust that everyone else sort of knows what they are doing on the roads and won't plow into you and kill you.

Life expectancy.
When you're a kid, everyone is old. I never thought much about the ages my grandparents were when they died. It's frightening to think about now as I get older.
They were 59, 62, 65, and 69 when they passed.

Just how cutthroat things tend to be in college and in the adult “at-will employment” world. I’m suspicious that this is a contributing factor to the mental health crisis.

Very few of us leave this world fully intact. I had a horrific wisdom tooth removal just as covid hit. It was extremely deep rooted, and the dentist was kind of a butcher (I did NOT have insurance so the job went to the lowest bidder). Took about an hour for the extraction; he had to break it into several pieces, and had to go back in AFTER sewing me up because he left some behind.
I do NOT do well with change, particularly changes to my body. It took me a few years to psychologically recover from the experience (a global pandemic and my overuse of cannabis at the time really didn't help any). I still have anxiety episodes every once in a while thinking about what part of me will fail or have to be removed next.
Also, American healthcare is a joke and a scam. That's pretty damn terrifying.
