A Sixty and Me report argues that common changes with age should not automatically be treated as inevitable or unexplained. It cites research on anemia, vitamin B12 and magnesium, while stressing that symptoms have many possible causes and require clinical evaluation.
A Sixty and Me report argues that fatigue, tingling and muscle cramps should not automatically be dismissed as normal aging, because some conditions that become more common with age have causes clinicians can assess and treat. The article draws on research about anemia and guidance from the National Institutes of Health (NIH), while emphasizing that symptoms can have many explanations and that readers should consult a health professional rather than self-diagnose.
The report points to a national survey conducted from 1988 to 1994, whose findings were published in the journal Blood in 2004. Researchers found anemia rates rose after age 50: about one in 10 women aged 65 and older were anemic, with the rate exceeding 20 percent among people aged 85 and older. Most cases were mild. The article says the researchers identified an iron, folate or vitamin B12 deficiency in about one-third of older people with anemia.
It also describes vitamin B12 as one possible contributor to fatigue and tingling. The NIH reports that atrophic gastritis, which can reduce B12 absorption from food, affects 2 percent of the general population and 8 to 9 percent of adults aged 65 and older. The NIH also says metformin and some acid-reducing medicines can affect B12 levels or absorption. Low B12 can cause fatigue and nerve symptoms, including numbness and tingling, which may occur even without anemia. These facts do not establish the cause of any individual’s symptoms.
Magnesium is another example in the report. The NIH says older adults tend to consume and absorb less magnesium and lose more through the kidneys; some medications can also affect levels. Early deficiency symptoms can include fatigue and weakness, followed in more severe cases by numbness, tingling and cramps. The NIH cautions that serum magnesium tests have limited correlation with total-body magnesium and that no single measurement method is considered satisfactory. A normal result should be interpreted alongside symptoms and medical history, not treated as a diagnosis by itself.
Why Symptom Attribution Matters
The report’s central point is not that aging explains no physical changes, but that a label such as “part of getting older” can prematurely end a conversation about symptoms. Some age-related changes are lasting, and some conditions become more common over time. But common does not mean there is no cause to investigate or no care that might help.
The article also cites a University of Michigan National Poll on Healthy Aging survey of 2,035 adults aged 50 to 80, conducted in December 2019. An analysis published in JAMA Network Open in 2022 found that 81 percent reported at least one ageist belief about themselves, including the idea that health problems are simply part of getting older. Those beliefs were associated with worse physical and mental health. The survey captured responses at one point in time, however, so it cannot establish whether the beliefs contributed to poorer health or whether people in poorer health were more likely to hold them.
For readers, the practical implication is a reason to ask questions—not a reason to assume a nutrient deficiency or request supplements. Fatigue, cramps and tingling can arise from many causes. A clinician can consider symptoms, medicines, history and appropriate testing together.

Evidence Behind the Aging Claim
The article opens with a line attributed to the Roman playwright Terence in his comedy Phormio: “Senectus ipsa est morbus,” translated in the report as “Old age itself is a disease.” It uses the line to frame a familiar modern response to forgetfulness, slower movement or other changes: “That’s just part of getting older.” The historical reference is framing, rather than the report’s medical evidence.
The health evidence comes from several sources with different limits. The anemia figures are based on a survey from 1988 to 1994, and the report does not present them as a current prevalence estimate. The B12 and magnesium information is attributed to the NIH. The ageism findings come from a survey and later analysis, not a trial showing that beliefs cause health outcomes. Together, the sources support asking about possible explanations; they do not show that any one symptom in a particular person has a specific cause.
“Senectus ipsa est morbus.”
— Terence, as quoted in the Sixty and Me report
What Symptoms and Tests Cannot Show
The source material does not identify a new clinical study or updated prevalence estimate; it is a report that brings together existing research and health guidance. It also does not establish how often symptoms dismissed as aging are actually caused by nutrient deficiencies. Fatigue, tingling and cramps are nonspecific, and the cited evidence cannot identify their cause in any individual.
The ageism survey cannot show cause and effect because participants were assessed at one point in time. The report also does not give a date for its publication. It warns against treating a normal lab result as a complete answer, particularly for magnesium, but does not suggest that symptoms alone prove a deficiency. Testing choices and their meaning depend on a person’s circumstances and clinician assessment.
Questions for a Medical Appointment
The article encourages readers who are concerned about symptoms to continue the conversation with a qualified health professional. It suggests asking what supports the conclusion that a symptom is age-related, what other causes have been considered, whether medicines could affect nutrient levels, and what a proposed test can—and cannot—show.
Readers should not diagnose themselves from the article or begin supplements without professional guidance. The report warns that supplements can interact with medicines and may cause harm at inappropriate amounts. The next step is an individualized discussion with a clinician, who can decide whether further evaluation or care is appropriate.
Key Questions
Does the report say fatigue and tingling are caused by aging?
No. It says these symptoms have many possible causes. Aging may bring physical changes and raise the likelihood of some conditions, but symptoms alone do not identify the cause.
Can vitamin B12 deficiency cause tingling without anemia?
The NIH information cited by the report says B12-related nerve symptoms, including numbness and tingling, can occur without anemia. That does not show that B12 is the cause for a particular person; clinical assessment is needed.
Does a normal magnesium blood test rule out a problem?
The report says the NIH considers serum magnesium a limited measure of total-body magnesium, and no single measurement method satisfactory. A clinician should interpret results with symptoms, medical history and other relevant information.
Should readers start magnesium or B12 supplements?
The article advises against starting supplements based on an article or without professional guidance. Supplements can interact with medicines and may cause harm at the wrong dose; discuss symptoms and options with a qualified health professional.
