What Aging Really Means—Beyond the Birthday Cake

By Shannon Kasun, Neuroscience Specialist

Each year, your friends and family gather to sing you an off-key rendition of Happy Birthday, throwing in some enthusiastic “cha-chas” and “hurrahs” for good measure. You sit there awkwardly during their performance (seriously, what are you supposed to do during that song?) before blowing out the flickering candles on your cake. You unwrap carefully packaged gifts, read heartfelt cards, and sift through tissue-stuffed bags. You reflect on the year behind you and dream about the one ahead.

This is the version of aging most of us are familiar with.

But what is aging, really?

Aging is the progressive deterioration of the physiological systems necessary for survival. Our birthday cake and present-filled version of aging is certainly more cheerful—but the biological reality is less festive.

Like any machine—a car, a boat—our bodies experience wear and tear simply by existing. Over time, this accumulated damage causes our systems to operate less efficiently, and eventually, dysfunctionally. This is a major reason why chronic health conditions like heart disease, arthritis, hypertension, and Alzheimer’s are more common as we get older: our biological systems are slowly breaking down.

But we don’t have to passively accept this decline.

Just as regular oil changes extend a car’s life, regular maintenance of our bodies—through exercise, proper nutrition, stress management, and restorative sleep—can extend not just how long we live (lifespan), but how well we live (healthspan). These habits help preserve physiological function, slowing the ticking of our biological clock.

Biological age refers to the true state of your body's systems—your cells, tissues, and organs—and may be older or younger than your chronological age. Essentially, it's a reflection of how well your body is holding up. For instance, two 50-year-olds could have vastly different biological ages depending on their lifestyle, environment, and genetics.

Research continues to affirm the power of lifestyle. Plant-based dietary patterns are associated with a slower pace of aging, while high-sugar diets tend to accelerate it (Wang et al., 2023; Chiu et al., 2024). Just 90 minutes of strength training per week has been linked to a four-year reduction in biological age (Tucker & Bates, 2024).

At CerePro Bioscience, we use cutting-edge biomarker analysis to measure your biological age. This personalized insight allows us to pinpoint how your body is aging and tailor the most effective interventions to help you stay strong, sharp, and resilient—today, and for years to come.

Because aging is inevitable, but how you age is, to a large extent, within your control.

So don’t keep blowing out your birthday candles just wishing for good health every year—take an active role in your aging journey. Your future self will thank you.
