How We Use It Now

Centuries later, that same dismissive sentiment echoes across modern doctors’ offices, living rooms, and internal monologues. Today, people routinely excuse memory lapses or a decline in physical stamina with a familiar refrain: "That’s just part of getting older." Friends and medical professionals repeat it with the same casual certainty that Chremes used in ancient Rome. It functions as an effective linguistic conversational stopper, sounding enough like a definitive answer that all further questions simply cease.

Picture a common scenario. A patient visits a physician, explaining that exhaustion weighs heavily on most afternoons, feet tingle persistently during the night, and painful leg cramps strike the moment relaxation finally sets in. Routine blood work returns within normal parameters, providing no glaring red flags. The doctor offers a kind, sympathetic smile and a reassuring explanation: "That’s just part of getting older." The dialogue ends, leaving underlying issues unaddressed.

What the Saying Gets Right

Human bodies undeniably change with time, and certain biological shifts are permanent and irreversible. Joints gradually wear down through decades of use, and aging eyes naturally require brighter light to read comfortably. When a physiological change cannot be reversed, modern medicine, targeted physical therapy, and supportive care can still significantly ease daily living and improve quality of life.

Furthermore, medical science acknowledges that specific health conditions do become statistically more prevalent as people age. Anemia serves as a prime example. Data from a comprehensive national health survey conducted between 1988 and 1994, which was subsequently published in the journal Blood in 2004, revealed that the prevalence of anemia rises sharply after age 50. Approximately one in every ten women aged 65 and older was found to be anemic, and that rate climbed past 20 percent among individuals aged 85 and older. Notably, the vast majority of these cases were classified as mild.

If cultural assumptions about aging stopped there, the adage would remain scientifically accurate. The core trouble lies not in the recognition that certain conditions are common among older adults, but in the dangerous implication that follows: because a health problem is frequently observed at a certain age, it must inherently lack any underlying cause worth investigating or treating.

What the Saying Leaves Out

The very same anemia study that documented rising rates among older adults also investigated potential underlying causes. In approximately one-third of the older individuals diagnosed with anemia, researchers uncovered a distinct nutrient deficiency—specifically a lack of iron, folate, or vitamin B12. These are tangible, identifiable causes that a physician can readily test for and treat effectively.

Vitamin B12 Is One Example

Nutrient absorption changes significantly over time, making deficiencies a hidden culprit behind vague symptoms. According to data from the National Institutes of Health, atrophic gastritis—a medical condition that severely impairs the body’s ability to absorb vitamin B12 from food—affects roughly 2 percent of the general population. However, that figure jumps dramatically to between 8 and 9 percent among adults aged 65 and older.

Commonly prescribed medications can also deplete vitamin B12 levels. The NIH reports that metformin, a widely utilized pharmaceutical treatment for diabetes, can hinder vitamin B12 absorption and lower blood concentrations. Similarly, acid-reducing medications frequently prescribed for gastrointestinal issues can interfere with the body’s capacity to extract B12 from dietary sources.

The NIH explicitly lists persistent fatigue among the hallmark symptoms of low vitamin B12 levels, alongside numbness and tingling sensations in the hands and feet. Crucially, these neurological symptoms can manifest entirely independently of anemia. Therefore, the afternoon exhaustion and tingling feet reported during a routine doctor’s visit could stem directly from a manageable vitamin B12 deficiency. Alternatively, they could originate from another source, but only proper medical evaluation and diagnostic testing can determine the true origin.

Magnesium Is Another Example

Magnesium represents another critical mineral frequently overlooked in aging populations. According to NIH findings, older adults consistently consume less magnesium through their diets than younger cohorts, absorb smaller amounts through the gastrointestinal tract, and excrete higher quantities through the kidneys. Additionally, older individuals are statistically more likely to take pharmaceutical medications that negatively impact magnesium balance.

Early warning signs of low magnesium listed by the NIH include general fatigue and muscle weakness. As the deficiency progresses, symptoms escalate to include numbness, tingling, and painful muscle cramps.

Diagnosing a magnesium deficiency presents unique clinical challenges. Standard blood panels measure magnesium levels solely within the serum, which is the liquid component of blood. As the NIH explicitly notes, serum magnesium levels demonstrate "little correlation with total body magnesium levels." Furthermore, the agency states that no single diagnostic method for measuring magnesium is currently considered entirely satisfactory. Consequently, a "normal" lab result is merely a single piece of data that must be interpreted in conjunction with a patient’s reported symptoms, medical history, and current medication regimen. The gap between a normal laboratory report and how an individual actually feels forms the crux of ongoing medical discussions about chronic, overlooked symptoms.

Fatigue and cramps have a wide array of potential origins, and a nutritional deficiency represents only one possibility. Each distinct symptom deserves careful clinical evaluation before anyone hastily concludes it is simply a byproduct of advancing age.

What the Belief Does to Us

Internalized societal attitudes toward aging have measurable negative consequences for physical and psychological well-being. In December 2019, the University of Michigan’s National Poll on Healthy Aging surveyed 2,035 adults ranging in age from 50 to 80 regarding their experiences with everyday ageism. An in-depth analysis of the data was published in JAMA Network Open in 2022. The findings revealed that an overwhelming 81 percent of the surveyed adults held at least one internal ageist belief about themselves, such as the fatalistic notion that "having health problems is part of getting older." Crucially, researchers found that holding these internalized beliefs was directly linked to worse self-reported physical and mental health outcomes.

Because the survey captured data at a single point in time, it cannot definitively establish direct causation or show which factor came first. It remains entirely possible that individuals already experiencing poor health are simply more inclined to attribute their struggles to the natural aging process. Nevertheless, the ingrained belief that every new ache, pain, or symptom is merely "my age talking" frequently discourages patients from seeking professional medical explanations.

A Better Question

When confronted with the dismissive phrase "That’s just part of getting older," patients can redirect the conversation by asking a more constructive question: What makes us confident this specific issue is exclusively caused by aging, and what alternative causes have we thoroughly considered?

Navigating this requires collaborative dialogue with a qualified healthcare provider. Patients are strongly cautioned against attempting self-diagnosis based on medical literature or initiating unregulated supplement regimens independently. Certain dietary supplements can dangerous interact with prescription medications, while others can cause direct physical harm if consumed in incorrect quantities. Keeping the conversation active with a physician ensures proper guidance until a definitive answer is reached.

More than two thousand years ago, the Roman statesman Cicero pushed back against the exact defeatist philosophy found in Terence’s comedic dialogue. In his philosophical treatise On Old Age, the elderly statesman Cato argued that the widespread physical weakness people carelessly attribute to advancing years actually stems from underlying poor health, asserting that society should resist the degradation of old age much like one would fight a progressive disease.

The same principle applies to modern medical complaints, from midday exhaustion to tingling extremities. Before anyone writes off chronic discomfort as an inevitable consequence of getting older, medical professionals and patients alike have a responsibility to look deeper for an underlying, treatable cause.
