According to multiple Taiwanese media reports, Dr. Li Long-teng, a 73-year-old family medicine specialist, appeared spirited and energetic in a recent interview. He remains active, practicing at hospitals including National Taiwan University Hospital, Hong-En Hospital, and Ren-Ji Hospital. Despite a busy schedule that often leaves him skipping lunch and even hesitant to take bathroom breaks, Li proudly states that since childhood, he has adhered to just three principles, maintaining his "no three highs" health status.
Longevity Habit 1: Consistent Sleep Schedule
Li maintains a strict routine of going to bed between 10:00 PM and 10:30 PM and waking up between 5:00 AM and 6:00 AM. He doesn't sleep in due to tiredness, nor does he stay up late. He even adhered to this during his college entrance exams, always being in bed before 11:00 PM.
Longevity Habit 2: Consistent Exercise
Li shares that he used to love running. Now at an older age, he has adjusted his routine to running one day and resting for three days, covering about 10 kilometers over those three running days.
Longevity Habit 3: Commitment to a Balanced Diet
Li aims for a daily macronutrient ratio of 60 percent carbohydrates, 25 percent protein, and 15 percent fat. However, he admits that with age, consuming too many carbohydrates can easily raise blood sugar levels, so he shifts his calorie distribution towards protein and fat. He shares, "Sometimes I have coffee and an egg in the morning. If I'm too busy to eat lunch, I must make up the nutrition in the evening." Therefore, he calculates his morning intake of carbs and fat and supplements the lacking protein in the evening.
Furthermore, he particularly enjoys eating wood ear mushrooms (black fungus) and celery. Besides being rich in dietary fiber, they help cleanse the blood and reduce the risk of stroke and myocardial infarction. Li points out that many people emphasize supplementing with lutein or beta-carotene, but simply eating colorful vegetables is sufficient—such as cauliflower, spinach, and carrots. He recommends eating at least one or two servings daily, about half a plate's worth.
Damaged Blood Vessels Can Lead to Stroke and Heart Attack: What Are the Symptoms?

According to information from the Hospital Authority, symptoms of acute myocardial infarction include:
- Chest pain or discomfort (sometimes radiating to the jaw and left arm)
