The Critical Distinction: Chronological vs. Biological Age
While your chronological age is the number of years you've been alive, it offers an incomplete picture of your health. A more accurate measure, particularly in healthy aging, is your biological age. Your biological age reflects the health of your cells and tissues, which can be influenced by various lifestyle and genetic factors.
What influences biological age?
- DNA Methylation: This process regulates gene expression and is a key marker used by researchers to determine biological age.
- Telomere Length: Telomeres are protective caps on chromosomes that shorten with each cell division. Shorter telomeres are associated with more rapid aging and health issues.
- Lifestyle Factors: Diet, exercise, sleep, stress management, and environmental exposures all play a significant role in determining biological age. Individuals leading healthy lifestyles often have a biological age younger than their chronological age.
This is why two people who are both 72 can have vastly different levels of health. One may be active and vibrant, with a lower biological age, while another may have multiple chronic conditions and a higher biological age. The label 'geriatric' applies to the latter, not the former.
What 'Geriatric' Really Means in Medicine
In the medical community, 'geriatric' is not a broad label for anyone over 65 or 70. Instead, it refers to a specialized field of medicine that focuses on the complex health needs of older adults. A geriatrician is a physician who assesses and manages conditions related to frailty, multiple chronic illnesses, and functional decline, regardless of a patient's exact age.
The Comprehensive Geriatric Assessment (CGA)
Instead of relying on a single number, geriatricians use a comprehensive geriatric assessment (CGA) to evaluate a patient's needs. This systematic, multidisciplinary process provides a much more holistic view than a standard check-up. The Geriatric 5Ms framework is a helpful guide for this process.
- Mind: Evaluating cognitive function and psychological well-being, looking for signs of dementia, delirium, or depression.
- Mobility: Assessing balance, gait speed, and fall risk, which is a major concern for older adults.
- Medications: Performing a detailed review of all prescriptions and supplements to manage polypharmacy (taking multiple medications) and identify potential interactions.
- What Matters Most: Understanding the patient's personal goals, priorities, and values to create a care plan aligned with their wishes.
- Multicomplexity: Recognizing and managing the interaction of multiple chronic conditions and social determinants of health, which can be particularly challenging for older adults.
Health and Wellness in Your 70s and Beyond
Your 70s can be a decade of continued activity and vitality. Proactive health management is far more important than worrying about a numerical age label. Adopting healthy habits can significantly improve your quality of life and potentially lower your biological age.
Tips for staying healthy
- Physical Activity: Engage in a mix of aerobic, strength, balance, and flexibility exercises. Aim for at least 150 minutes of moderate-intensity activity weekly. Walking, swimming, and gardening are excellent options.
- Nutrition: Focus on a balanced diet rich in fruits, vegetables, whole grains, and lean proteins. Pay attention to calcium and Vitamin D intake for bone health.
- Mental Engagement: Keep your mind sharp by reading, learning new skills, or playing word games. Mental stimulation is linked to better brain function.
- Social Connection: Combat loneliness and isolation by spending time with family and friends, joining clubs, or volunteering. Strong social ties improve both mental and physical health.
- Regular Check-ups: See your doctor for routine check-ups and screenings. Managing chronic conditions like high blood pressure and high cholesterol is crucial for long-term health.
Comparison: Senior Citizen vs. Geriatric Patient
| Criterion | Senior Citizen | Geriatric Patient |
|---|---|---|
| Definition | A general, social, or legal term for an older adult, often defined by a chronological age cut-off (e.g., 65+) for benefits. | A medical term for a person with complex health issues associated with aging, regardless of exact age. |
| Basis | Chronological age. | Functional status, health complexity, and frailty. |
| Context | Discounts, eligibility for social programs like Medicare, societal perception. | Clinical evaluation and specialized medical care, focusing on holistic health. |
| Focus | Age-based access to resources. | Patient-centered care to preserve function, independence, and quality of life. |
Overcoming Ageism in Healthcare
Prejudice or discrimination against people based on age is a real issue in healthcare. Labeling someone 'geriatric' solely based on their chronological age can lead to assumptions about their health, capabilities, and cognitive function. This can result in substandard or less proactive care. A patient-centered approach, guided by a CGA, ensures care is tailored to the individual's specific needs, not their date of birth.
Healthcare providers have a responsibility to address ageism by focusing on functional ability and individual health complexity, not just age.

Conclusion: A Shift in Perspective
Ultimately, whether is 72 considered geriatric? depends entirely on the context. In a social sense, a 72-year-old is a senior citizen. In a medical context, however, it is a clinical assessment based on overall health and function, not a number. The most important takeaway is that healthy aging is a proactive process. Focusing on lifestyle, wellness, and personalized care, rather than a calendar, is the key to living a long and independent life.
