Mechanic of the Human Body

The patient looked at the one-page guides on diet, nutrition label reading, and exercise recommendations that I’d given them as we went over those topics. They, like so many of us, could improve their diet and exercise routines to optimize their health. The patient stood, ready to leave the exam room. They paused before we entered the hall. “Thanks for caring. You’re the first doctor who talked about all this,” they said.

“Of course, that’s my job!” I said. I let their comment sit. They were over 50 years old. What had their doctors talked about throughout the years if not these topics?

I reflected on how exciting and challenging it is to be a mechanic of the human body – something I’ve come to consider myself as I settle into my work as a primary care physician. I think the analogy best describes the role I play in my patients’ health and lives.

As a mechanic of the human body, I don’t have control over many things.

  • I can’t control the make or model (the body type, age, or genetics) my patient has.
  • I can’t control the road they drive on or how that road is maintained (the patient’s life journey).
  • I can’t control the obstacles and dangers on the road they follow (the unexpected challenges that are the metaphorical equivalents of a deer jumping in front of their car or a patch of black ice).
  • I can’t control how much money they have to fuel, maintain, and optimize themselves.
  • I can’t control how they fuel themselves (food or otherwise) and how often or at what speed they go for a spin (exercise).
  • I can’t control how the world treats them (the metaphorical equivalents of sunshine on paint and potholes on tires).
  • And I can’t control if my patient implements the maintenance and repair suggestions I give them (the lifestyle tweaks to optimize health, the medications, and so on).

As a mechanic of the human body, I can control a few critical things.

  • I can control what I say about my patient’s health.
  • I can control when I give advice, allow reality to just be, or offer praise for success.
  • I can control where I recommend we focus in terms of health optimization and next steps for improving or maintaining their health.
  • I can control how I listen. How I talk. How I behave.

Health is complicated. It’s not just about what a person does, though work, exercise, diet, and relationships play a huge role in health. Health is a lot about luck – the genetics, place of birth, and family culture and wealth fate gave a patient. Health is a lot about environment – exposure to toxins, discrimination, kindness, and education. Health is a tiny bit about interactions with the healthcare system and medications. That said, most of what I listed is out of a patient’s control. This means, while many health challenges are rooted in genetics and environment, the only health improvements that are possible are what a patient does (from taking their medications to increasing exercise, as examples).

Alleviating and eliminating most medical problems begins with making lifestyle adjustments. There are few people in the US who can’t improve something about their lifestyle to further optimize their health. After lifestyle we have medications, procedures, and surgeries. But we don’t have medications, procedures, and surgeries for everything…which means… sometimes… the only thing a patient can do to improve their health is make the best lifestyle choices they can.

When I reflected on my patient’s comment, I was not surprised that lifestyle changes had not been a huge focus of their previous discussions with doctors. Healthcare is rushed. But, more than anything, lifestyle is the hardest thing to teach and talk about. It is harder to explain and change patients’ lifestyles than it is to prescribe medications. It’s fitting that lifestyle is hard to teach because lifestyle adjustments are also the hardest thing for patients to do consistently. Just as it is hard to follow traffic laws and speed limits every time one drives, making the best decision for one’s health every time one acts requires vigilance and strength. It takes constant effort to choose the healthy option and resist the other options. As a mechanic of the human body, I can’t make lifestyle choices for my patients. All I can do is provide maps and information to help them decide how and where they wish to go. Challenges and all, I’m excited and humbled that my patients chose me to join them on their health journey, one-page educational guides and all.

Onto the Next Adventure

It’s been a few months since I wrote. The time passed quickly for me. On June 30, 2026, I finished internal medicine residency. Earlier this month, I took my internal medicine board exam (national exam proving what I learned during residency). Finishing residency and taking my board exam marked the end of the #DoctorhoodQuest. The Doctorhood Quest was a 10-year journey starting with pre-medical classes, then medical school, and (lastly) residency and my national board exam. In those 10 years, I worked with 100s of doctors, 100s of patients, and did 1000s of exam/practice exam questions. Next up, the #DoctorTrail. In just a week, I begin my first job as an independent doctor. I’ll be a primary care physician in the Richmond, VA area.

I thought about writing often as the past few months passed; yet I needed to get through the end of the quest before I could share my thoughts. The day I turned in my residency badge and walked out of the hospital where I did residency was like the day I finished my Peace Corps service and I got on a plane to return to the US after years living in Paraguay. One door closed forever while another actively sprung open. My emotions were a mix of pride, excitement, nervousness, and hope.

Every doctor has their own reason for starting the Doctorhood Quest. Mine wasn’t because I wanted to go to medical school or do residency. Despite the amazing people I met and the unprecedented amount of knowledge I gathered during my years of doctor training, the journey was long and mostly unpleasant. I started the Doctorhood Quest for this new phase: to be a doctor. Being a doctor captivated me because of the opportunity to positively influence others’ lives and change the world with one micro-action at a time. I’m also excited to be a doctor because no other profession I know of holds my attention as well as the ever-changing world of medical science. Today, and until I retire, I am on the #DoctorTrail. I’m not sure what that trail will be like. I imagine that it’ll be steep and harrowing at points. At other times stunning. And at others it might be boring. Just like the 100s of miles I’ve hiked in my free time, no two miles will be the same.

My residency program had us write a letter to ourselves a few days before we officially started our resident duties. The program director gave us the letters at graduation. We often think about the expertise of doctors. Yet, it’s important to remember the human side of doctors too. So, here’s the letter I wrote before I launched residency. The advice I gave myself then holds true now as I prepare to start the latest adventure: primary care physician.

June 29, 2023

Dear Future Self,

You start on the wards* as an intern** in 2 days. You’re a mix of nervous, excited, happy, and terrified. Despite the mix of emotions, the overall mood governing these days of anticipation is positive. You’re looking forward to gaining the confidence, knowledge, and experience to manage most patients on your own. You’re looking forward to belonging to a team, being part of a community, getting paid, and having ownership of your work. You’re worried about balancing the long work hours of residency with the rest of your life. Especially because “the rest” involves so much and is central to who you are – exercise, writing, David, food, travel, friends, art, and the natural world to name a few things that make up “the rest.”

It’s hard to give your future self advice. I’ll just tell you some things that seem important as I write this and that I hope you remember.

  • I hope you keep with you, at the core of your work, how much you love patients, their families, and their stories.
  • I hope you remember the joy that comes with working in a team when each member bothers to care.
  • I hope you remember your love of balance.
  • I hope you remember how brave you already are.
  • I hope you remember that calmness is the best place to start, even in the worst situations.

I can’t wait to see what you accomplish by the time you read this.

Stay strong,

Jett

As I say goodbye to the #DoctorhoodQuest and begin the #DoctorTrail, I’m reassured that I accomplished the goals related to learning that I set out for myself at the beginning of residency. Of course, there is always more to learn. The endless potential for growth is an important reason for why I entered medicine. The trail will be challenging as I settle into my new role as an independent physician. But I know that I’m ready. I find myself happy and excited. I remember why I’m here and what’s important. My trail shoes are tied. My pack is full. I’m stoked for the adventure that awaits on the Doctor Trail.
