We are now in the high income group often aging fast, your hormone levels, especially sex hormone issues, you are 40 years old, but your hormone levels in your body may be 50 years old. We are not the same as the United States, we are high income tend to age faster, they tend to be high income tend to live longer, we have to think about why the difference. Each person has three ages: 1. natural age, that is, the actual number of years; 2. physiological age, that is, whether the physiological functions, muscle, heart function, etc. match the age. 3, mental age, that is, whether your heart is young. According to statistics, the hormone level in the body of high-income people aged 30-50, i.e., the physiological age of 40 years old, may be the natural age of 50 years old. Half of health is mental health: half of health is mental health and half of disease is mental illness. I understand this stuff myself, seeing the patient, seeing their attitude towards the disease and his state, this is a very important aspect. And nothing can make a person’s life shorter than bad emotions and bad state of mind, such as worry, fear, greed, jealousy, hatred. There is a close relationship between tumor and state of mind: people produce more than 3000 cancer cells a day, most people will not get tumor because the NK cells in the blood will kill these cancer cells. However, a person who is depressed and in a very bad mood all day long will have a decrease in NK cell function and a 20% decrease in immune cells and spontaneous combustion killer cells. All of these are closely related to the psychological aspect.
