Gen Z Is Aging Faster Than They Should… And Boomer Stress May Be Why

Gen Z is often accused of refusing to grow up, but commentary YouTuber Casey Simpson argues that the generation is dealing with something more complicated: young adults who feel emotionally stuck in adolescence while simultaneously carrying levels of financial and social stress that may be taking a physical toll.

In a recent video, Simpson connected research on biological aging with TikTok clips from young people struggling to find work, build savings and figure out what adulthood is supposed to look like. His broader argument is that Gen Z inherited an economy that makes traditional milestones harder to reach, while also growing up in a more sheltered, anxious and digitally fragmented environment than earlier generations.

That combination, he suggested, has created a strange contradiction. Gen Z may feel younger than previous generations did at the same age, yet some researchers are finding signs that younger adults are biologically aging faster.

Simpson Says The Health Research Is Alarming

Simpson opened with research he described as showing unexpectedly high rates of certain cancers among younger adults, alongside evidence of a growing gap between chronological age and biological age.

According to Simpson’s summary, researchers studying blood markers from more than 150,000 adults found that people born between 1990 and 1999 showed a much larger biological-age gap than people born several decades earlier.

He said the findings raised an obvious question: why would a generation that generally smokes less and has benefited from improvements in environmental safety still show signs of accelerated aging?

Simpson’s answer was stress.

He argued that chronic stress can affect health throughout the body and suggested that the pressure Gen Z experiences may be contributing to the problem.

Those are serious medical claims, and the exact relationship between stress, biological aging and disease is more complicated than any one YouTube explanation can capture. Still, Simpson used the research as the foundation for a larger cultural question about why so many young adults say they feel exhausted before their lives have fully begun.

Young People Say They Already Look Older

One TikTok creator featured in the video joked that people routinely assume he is much older than his actual age.

He said he was 26, yet strangers had mistaken his mother for his younger sister and assumed references to his “family” meant his own children rather than his parents.

The story became even more absurd when he recalled asking Dwayne Johnson for an autograph and being treated as though he were an older father collecting it for a child.

Another Gen Z creator admitted, “I’m 25. I’m not even going to pretend like I look like what a 25-year-old should look like.”

Simpson contrasted those anecdotes with his own experience of being mistaken for someone much younger, but he said the wider conversation about Gen Z looking older had taken off because it connected with something many young adults already feel.

The appearance debate may be subjective, but the underlying anxiety is not. A generation constantly comparing itself with older people who already had careers, homes and families at the same age can easily begin feeling as though time is moving faster than progress.

The Job Market Is Making Young Adults Feel Behind

One of the most persuasive parts of Simpson’s argument came from young people describing how difficult it has become to begin a career.

A woman in one clip said she graduated in May 2024 with a bachelor’s degree in data science and strong reviews from a post-graduate internship, yet more than two years later she still had not landed a full-time job in her field.

She was speaking while heading into an interview for a retail position.

Another commenter said they were already on a fourth internship despite graduating from a top university.

Simpson contrasted that with stories from earlier generations, including a grandfather who reportedly began working as a chemist before even attending college.

The comparison was partly played for laughs, but Simpson’s point was serious: the entry barrier into professional work has become dramatically higher, while degrees no longer guarantee the transition into stable employment that young people were often told to expect.

A TikTok creator later pushed back on accusations that Gen Z is lazy.

“I would work if I could get a job,” the creator said, arguing that young people are sending applications into hiring systems increasingly filtered by automation and often receiving no response at all.

That kind of uncertainty can create a particular form of stress because there is no clear action that guarantees progress. Working harder does not necessarily mean moving forward, and that can make people feel powerless.

Housing And Debt Make The Boomer Comparison Worse

Simpson also argued that older generations sometimes underestimate how dramatically the economics of adulthood have changed.

He said Gen Z households are working far more combined hours than households in the 1960s, with many young adults also taking side jobs or freelance work, yet still struggling to accumulate wealth.

He attributed much of that gap to housing prices, student loans, health-care expenses and transportation costs.

According to Simpson, homes once cost a much smaller multiple of household income, while younger adults now face prices that can require two incomes just to consider buying.

He was particularly critical of baby boomers who tell younger people they simply need to work harder, arguing that many members of that generation entered adulthood when one income could support a household and homeownership was far more accessible.

Simpson also blamed restrictive housing policies for limiting supply and pushing prices higher for the people who came afterward.

His generational framing is broad, and individual boomers obviously had wildly different economic experiences. Still, the underlying frustration is easy to understand: young adults are being measured against milestones achieved under conditions that no longer look the same.

Gen Z May Be Sheltered And Overwhelmed At The Same Time

Simpson did not blame everything on the economy.

In fact, he argued that many Gen Z children were given less independence than earlier generations, leaving them poorly prepared for ordinary stress once adulthood arrived.

Previous generations, he said, often walked places alone, resolved conflicts without parents immediately stepping in and were expected to navigate more of daily life independently.

By contrast, some Gen Z children were not even allowed to walk a few blocks to a friend’s home until their early teens.

One commenter said their mother kept them inside so much that they effectively missed the childhood phase of casually playing outdoors with friends.

Simpson believes that matters because responsibility teaches people that their decisions carry weight. If every meaningful choice is delayed or handled by adults, smaller decisions can begin feeling far more threatening later.

He pointed to young adults who struggle to choose a movie, become anxious all day because they have a late-afternoon appointment, or wait for someone else to tell them what to do.

That part of his argument may sting because it places some responsibility back on Gen Z itself. Economic conditions can be genuinely hostile while personal habits still make those conditions harder to navigate.

Short-Form Media And Lockdowns Added Another Layer

Simpson also blamed the digital environment Gen Z grew up in, particularly short-form video.

Earlier generations, he argued, usually consumed stories that required sustained attention, whether through books, films or television episodes.

Gen Z can spend the same half hour scrolling through dozens of unrelated clips, training the brain to expect constant novelty without requiring much commitment to any one idea.

He suggested that this contributes to the sense that nothing feels meaningful for very long.

Then came the pandemic lockdowns, which Simpson believes disrupted the transition into adulthood for a generation that was already struggling with independence.

He pointed to posts from people in their mid-20s who still emotionally identify with the age they were in early 2020, as though several formative years blurred together.

That feeling of lost time appears repeatedly in Gen Z discussions. People know the calendar moved forward, but many say their lives did not develop through the normal milestones they expected during those years.

Simpson Says The Answer Is More Responsibility, Not Less

Despite spending much of the video describing the forces working against Gen Z, Simpson did not end by arguing that young adults are helpless.

He said people need to make decisions, accept imperfect outcomes and begin taking responsibility even when they are uncertain.

His argument was that choosing a bad job can be better than endlessly waiting for the perfect one, because even a poor experience teaches something and creates momentum.

The same principle, he said, applies to careers, relationships, cities and other major life choices.

Potential by itself has little value if someone never turns it into anything concrete.

Simpson also discussed research he interpreted as showing that people who view stress as something they can learn from may handle it better than people who see stress only as harmful.

His conclusion was less about eliminating stress than regaining a sense of agency over it.

That may be the most useful part of his broader argument. Gen Z inherited real economic problems, a difficult job market, expensive housing and a childhood shaped by extraordinary levels of digital stimulation and social disruption, but none of that means young adults have to remain frozen while waiting for conditions to become ideal.

Simpson sees Gen Z as a generation caught between childhood and adulthood, stressed enough to feel old but often too uncertain to feel fully grown.

The challenge, in his view, is not pretending those pressures do not exist. It is learning to move forward despite them, so adulthood becomes something young people actively build rather than another milestone they keep waiting to feel ready for.
