How Genetics and Mindset Can Shape Your Approach to Aging

If you could go back and ask your five-year-old self what you wanted to do when you grew up, the answer probably wasn’t “pharmacist.” For me, though, that was it—the pharmacy was my playground and purpose, and I built my life around both traditional medicines and the promise of new advancements. But as the years unfolded and both my own health and my family’s took unexpected turns, I realized there’s far more to health and aging than the pills and potions that line a drugstore shelf. Today, I want to talk about a topic close to my heart—and to my DNA—why our genetic makeup doesn’t have to dictate our health destiny and how we can use both genetic insight and mindset to rewrite the narrative on aging.

Aging, Illness, and Determinism: Are We Really Prisoners of Our DNA?

This is a question I’ve wrestled with, not only as a healthcare professional but as a patient, a parent, and a son. There’s a deeply rooted belief out there that aging is a one-way ticket to chronic illness, and that whatever’s in our genes is an unavoidable fate. But the reality is much more nuanced—and hopeful.

“Now, the purpose behind the genome originally, yes, was to understand human genetics, but to understand it from the point of view of illness. And just for your information, only about 4% of all the diseases that we deal with actually have their root cause in genetics. The others have their root cause in lifestyle and other things.”

So, what does that mean for the rest of us—the 96% whose health outcomes are determined by a blend of environment, choices, and, yes, mindset? It means that you’re not as locked in as you might think. Imagine that: you might have risk factors, but that’s not the same as a diagnosis chiseled into stone.

The Trap of “Fatalistic Aging”

It seems that as a society, we sometimes let go of the steering wheel too soon. I still remember a passing remark that captured how a lot of us feel about aging:

“As a matter of fact, just recently, someone said to me, it’s not a matter of the fact that you’re going to pass away from something. It’s just what are you going to get and when it’s going to happen.”

But that’s a belief that doesn’t serve us. It keeps us passive, waiting for the hammer to drop instead of picking up the tools to build something better for ourselves. The science—and my experience—tell a different story.

The Role of Genetic Testing: Know Your Genetic Blueprint

Here’s where modern science hands back some of that control. When my two brothers passed away from complications of diabetes—a disease we thought we knew inside-out—I was shaken to my core. I went to a naturopath, who suggested a DNA test. What I learned transformed everything:

“I had a DNA test done. It’s a very simple test. … I discovered that if I worked at it, I could be diabetic. But I wasn’t destined to go down the same path as my brothers.”

This is an important distinction: genetics can reveal your susceptibility, not an inevitability. You may have genes that make certain health challenges more likely, but in most cases, they’re switches that need to be flipped by lifestyle, environment, and stress. The right knowledge can show you where your efforts matter most.

How to Use Genetic Information for Your Health

• Understand Your Risks: Genetic reports may highlight higher risks (for instance, Diabetes Type 2 or cardiovascular sensitivity). Knowledge here isn’t about inducing fear—it’s about awareness and strategic action.
• Tailor Your Lifestyle: If your DNA says you’ve got a slower caffeine metabolism or a unique sensitivity to fats, you can optimize your nutrition accordingly. This is a level of personalization never before possible.
• Sharpen Your Focus: Health screenings, dietary tweaks, or stress reduction techniques can be honed in response to your unique genetic blueprint, making preventive care far more effective.

But remember: even the sharpest insights are wasted if we don’t put them into practice.

Life Expectancy and Mindset: The Power of Your Perspective

There’s another layer at play here—how we think about aging and health fundamentally shapes our outcomes. When I started in pharmacy, I believed in “a pill for every ill,” but over time, I began to question whether medicine alone could give us the vibrant longevity we crave.

“…this crack of, do we have all the answers, kind of started to grow. So when I got really sick and there was no answers to that, I recovered, obviously, and went back to my job. But I had this nagging feeling in the back of my mind that something was missing.”

How Mindset Directly Impacts Aging

• Defensive vs. Proactive: Are you waiting for disease to show up or actively building resilience in body and mind?
• Growth Over Fate: Mindset research shows that people who see health as modifiable are more likely to adopt habits that pay dividends in later years.
• The Value of Purpose: A sense of meaning, connection, and forward momentum is one of the most powerful predictors of longevity. People who love what they do (even working “100 hours a week,” as I once did!) often have a resilience that numbers can’t fully explain.

Strategies for Proactive Aging—Blending Genetics and Mindset

1. Get Informed

   Consider having your DNA tested—this isn’t about finding out your fate, but instead, learning how you can take smarter action. There are reputable, accessible platforms that deliver insights you can use with a health professional or functional medicine provider.

2. Personalize Your Plan

   Don’t rely on generic advice. Take your unique risk factors into account—both those you’re born with and those shaped by your environment. For example, if your family history is rich with diabetes, lean into blood sugar management, but know you’re not “doomed.”

3. Cultivate a Growth Mindset

   Drop victimhood for curiosity: How can I improve my odds? What’s within my control? Remember, your daily choices—nutrition, exercise, connection with others, stress management—can change the way your genes are expressed.

4. Integrate Support

   Work with trusted professionals: a pharmacist, a functional or naturopathic doctor, a health coach. Build a circle of support, because as strong as mindset is, community can be just as powerful.

Taking Control: Aging With Agency, Not Anxiety

My years behind the drugstore counter taught me the value of scientifically sound medicine, but my own health crises (and those of my family) convinced me that simply throwing pills at problems is never the complete answer. The genetic revolution gives us clues, but it’s our approach, attitude, and daily decisions that turn those clues into a game plan for genuine vitality.

“I loved getting to know my patients. I loved getting to know their situation. And I loved helping them. … It gave me some insight into the fact that there’s maybe a little bit more to pharmacy.”

The takeaway? You are not at the mercy of your DNA. Most chronic illnesses are not written in your genetic code, but rather in the tapestry of everyday choices you make. When you blend genetic knowledge with a proactive, hopeful mindset, you put yourself in the driver’s seat—whatever your age.

Call to Action

If you’ve ever stared down your family history and worried you’re next, shift your gaze: toward your choices, your mindset, and the health possibilities within reach. Consider DNA testing as a tool, not a verdict. Spend time learning, reflecting, and acting—because when it comes to genetics and aging, you have every reason to believe the best is yet to come.
