Annual Checkup – The Blood Test

Peter Lee

In Toronto, people undergo a full medical checkup every year, and among all the tests, the blood test is perhaps the most important one. In the past, I treated it as a routine. I never paid much attention to the report—if the doctor said, “You’re fine,” that was enough. But recently, after noticing some minor health issues and seeing a few “red marks” on my blood report, I began to look more closely—and to think more deeply.

As I studied the report, I was amazed by what I found. Each blood index—white cells, red cells, electrolytes, enzymes—operates within an incredibly narrow range. A tiny deviation, up or down, can trigger illness. It’s astonishing. Years ago, I worked as a process control engineer in a large petrochemical plant, maintaining distributed control systems. Now I realize: the human body is itself the most complex and perfect control system ever designed. It regulates countless parameters with precision far beyond any industrial system. While industrial systems require constant maintenance, calibration, and adjustment, the human control system runs effortlessly for decades, self-regulating and self-healing. Such perfection leaves me in awe of the Creator’s genius.

Blood is the river of life. Every organ and tissue depends on it for metabolism and renewal. Together, blood and vessels form a vast and delicate “inner ecosystem.” When this internal environment is healthy and balanced, the body thrives. Take hemoglobin, for instance—if its level drops, anemia follows, potentially affecting fetal development, increasing heart rate, raising blood pressure, and burdening the kidneys and brain. And hemoglobin is only one of many indicators. Each number on the report represents a vital thread in the web of life.

Illness, in truth, is not punishment—it is an early warning. These warnings begin subtly, almost imperceptibly, and then grow louder. Those with awareness can sense the early signals and make timely adjustments in lifestyle and mindset, restoring balance before real damage occurs. But those who ignore them may cross the invisible line—the compensation period. During this phase, when one organ weakens, another compensates by overworking to keep the system stable. Yet once that threshold is crossed, the blood chemistry can no longer be normalized, and the internal ecosystem begins to fail. Recovery then becomes far more difficult.

Ultimately, the human body is a masterpiece of divine engineering. Its blood chemistry, so precise and self-regulating, bears silent testimony to the mystery of creation. The body’s subtle alarms are gentle reminders—to pause, to listen, to realign. Our physiology is not just a biological phenomenon; it is also a sacred signpost, guiding us toward reverence, humility, and awe before the miracle of life itself.
