Is 35 the Gateway to "Aging"? The Reality of the "Age Limit" Imposed by Generation Z

1. Introduction: Why Did the "35 = Old" Comment Cause an Uproar?

On July 21, an article from the Australian newspaper The Age was published with the headline "Gen Z Declares People Are 'Old' at 35," sparking a flurry of mixed reactions on social media. The basis for this claim was an online survey conducted by the academic writing service Edubirdie. According to the survey, 22% of Gen Z respondents said "aging starts at 35," while another 26% said "40 is the limit."honey.nine.com.au

Among Millennials, 35% gave the same response (40 years old), and shockingly, nearly half of all respondents, regardless of generation, considered "under 40 = old."New York Post

2. Who Are Generation Z?

Gen Z is generally defined as those born between 1997 and 2012 (ages 13 to 28 in 2025), known as the "digital native" generation.Wikipedia
Surrounded by smartphones and social media from a young age, they have consumed timelines that glorify youth, crafted by algorithms, as naturally as breathing. As a result, for them, "young = valuable" has become an inherent assumption.

3. The Pros and Cons of "Youth Capitalism"

The influencer marketing market is expected to surpass $50 billion by 2024, with the advertising industry holding "youth engagement" as its golden rule. Platforms promote short-form videos like reels and shorts, amplifying "attractive appearances" through algorithms. The reason Gen Z feels "old" earlier may largely be because they are consumed as fuel for buzz.

4. The Spread of #35IsTheNewOld on Social Media

Immediately after the article was published, "#35IsTheNewOld" trended on X. Posts expressing mixed emotions, such as "I'm 35 and still commute on a skateboard" and "I'm 27 and my junior colleagues treat me like I'm from the 'Showa era,'" exceeded 200,000 in a day. The most reposted was a self-deprecating tweet from a 30-year-old American man saying, "30 is the halfway point of life, I realized I was old at 27," which received a flood of sarcastic replies.New York Post

On Reddit's r/GenZ thread, a post titled "Why does your generation act like life after 30 is Grandmaville?" surged in popularity, garnering over 3,000 comments.Reddit

5. Australian TV Shows Join the Fray

On the Australian morning show Today Extra, TV host Shelly Horton (52) laughed off the issue, saying, "Gen Z: you do you, boo. I'm having the time of my life," eliciting laughter from the studio.honey.nine.com.au

Critic Sean Szeps joked, "105 should be the threshold for old age," while pointing out that "cringe culture" is stifling Gen Z's potential.honey.nine.com.au

6. Resonance with Japan's "35-Year-Old Problem"

In Japan, phrases like "35-year-old job change limit" and "aging line for childbirth" have been discussed as barriers in careers and life events. On Yahoo! Chiebukuro, posts by men in their early 30s asking "Is 34 already middle-aged?" regularly rank high, making age-related anxiety visible.

Additionally, many women express concerns about reaching 35 without getting married, showing that the tendency to measure self-worth based on age is not unique to Japan.Yahoo! Chiebukuro

7. Perspectives from Psychology and Sociology

Research suggests that Gen Z, having grown up exposed to uncertainties like pandemics, economic recessions, and wars, is more prone to a decrease in self-efficacy. The stronger the anxiety, the more sensitive they become to "death" and "aging," often setting their "safety zone" in youth. On the other hand, generational researchers argue that "the 30s are a period of rapid growth in social and human capital," and fear of aging is an unnecessary self-restriction.

8. The "Real Aging" According to Data

The WHO defines those aged 65 and over as elderly, and many medical reports indicate that significant physical aging becomes apparent around age 70. Nonetheless, the fact that half of Gen Z views those under 40 as "old" reveals a significant gap with statistics. "Aging" is increasingly becoming a socially constructed concept rather than a biological one.

9. The Millennial Counterattack: "OK Zoomer 2.0"

In Millennial communities, "OK Zoomer" has resurfaced as a counter to the "OK boomer" trend that went viral in 2019. Stamps with the ironic message "Someday you'll be someone else's 'Zoomer'" are trending, adding layers to the generational battle.Wikipedia

10. Impact on Business

In the marketing field, discussions are accelerating about targeting anti-aging products to those as young as 25 if people are considered old at 35. However, advertisements that excessively fuel age-related anxiety may be subject to regulation, necessitating a reconstruction of advertising ethics.

11. Expert Interviews: How to Deal with "Age Aversion"

Clinical psychologist Mariko Sakaguchi advises that age-related anxiety is a combination of decreased self-efficacy and fatigue from social media comparisons. She suggests reframing focus from the anxiety of "not having enough time" to what one is "currently achieving." Corporate HR consultant Yasuo Miyamoto also encourages not giving up on challenges due to age, stating, "The 30s are the golden age for job crafting."

12. Future Predictions: Will the "45-Year-Old Problem" Arise by 2035?

Generational theories are rewritten every 10 to 15 years. By 2035, when the Alpha generation enters society, it's likely that Gen Z (then aged 35 to 48) will face the brunt of "aging" concerns. The baton of age-related anxiety is always passed to the next generation—this is the nature of history.

13. Conclusion: Let's Talk in "Stories" Rather Than "Ages"

Whether 35 is considered old is more a matter of narrative than statistics. While the "youth myth" created by media and social media is powerful, we have the ability to re-edit our own stories. Building communities that share experiences across generations, free from numerical constraints, will be key to overcoming age-related anxieties.
