Ten Characteristics of Health Self Testing

I feel 13 years younger than my actual age. A survey of 500 elderly people aged 70 and above showed that feeling 13 years younger than their actual age is an important factor in longevity. Yaki Smith, a psychology professor at the University of Michigan, said, "Feeling young and healthy can enhance optimism and confidence in overcoming difficulties, help reduce stress, strengthen the immune system, and lower the risk of illness."2. Keep up with fashion. A survey in the United States shows that many centenarians send emails, search for lost friends on Google, and even date online. Researchers point out that the latest technology not only helps elderly people stay intellectually active, but also enhances their social skills.3. Menopause begins after the age of 52. Multiple studies have shown that naturally delaying menopause means an increase in lifespan.

4. Low daily calorie intake.

American researchers have found that people who limit their daily calorie intake to 1400 to 2000 calories have the same heart function as those who are 15 years younger than them.

5. Pulse 15 seconds 15 times. The majority of people have a resting heart rate of 60-100 beats per minute, and the fewer heartbeats, the healthier the body. Dr. Leslie Cho, director of the Women's cardiovascular Center at Cleveland Clinic, said that a slower heart rate means that the heart does not need to work too hard to complete the task of delivering blood.

6. Do not snore. A study conducted over 18 years found that the lifespan of normal individuals is three times that of patients with severe sleep apnea syndrome. 7. After menopause, the abdomen becomes flat. According to a study by the American Institute on Aging, women with a fuller waist face a 20% higher risk of death compared to the general population.

8. High levels of vitamin D in the blood. The vitamin D content in each milliliter of blood should be maintained at least 30 micrograms or more. Vitamin D can not only reduce osteoporosis, but also lower the risk of cancer, heart disease, and infectious diseases.

9. Outgoing personality. A recent study in Sweden shows that individuals with outgoing personalities have a 50% lower risk of developing dementia and are less susceptible to external stress. This is related to the low levels of cortisol in their brains. There are multiple measures to reduce cortisol levels, such as regular meditation, drinking black tea, and taking a nap.

10. Run for 40 minutes every day. After tracking runners and non runners for 21 years, California scientists have concluded that middle-aged people who run for 40 minutes a day have longer lifespans and stronger cognitive functions.
