How to calculate people's age correctly?

Mainly depends on how you want to calculate, generally the following three algorithms.

Nominal age

China's customary age calculation method is based on the calendar year after birth, that is, even if he was born in 1 year, he will increase 1 year every New Year. Generally calculated according to the lunar calendar, but also calculated according to the Gregorian calendar. For example, a baby born at the end of 65438+February is 1 year after birth, or 1 year after the Gregorian calendar or the local Chinese New Year. In this way, the baby is only a few days old and is already 2 years old. This calculation method is practical.

one-year-old

Also known as full age, it refers to the number of anniversaries or birthdays experienced from birth to calculation. For example,1A census was conducted at 0: 00 July 1990, and1A baby born in February 1989, with a nominal age of 2 years. Actually, it's just been more than six months, and I haven't celebrated my birthday yet. According to one year old, it should be less than 1 year old. One-year-old age is often 1 ~ 2 years younger than the nominal age, which is a commonly used age calculation method in population statistics.

One year old-0 years old at birth, every Gregorian birthday 1 year old.

Exact age

Refers to the days from the date of birth to the date of calculation. It reflects people's real life time more accurately than one-year-old age, but it is rarely used for demographic statistics because of its complicated statistical summary. In real life, except for babies under 1 year, especially newborns under 1 month, people usually don't calculate the exact age by day.

In the monograph of soul medicine, there are four ways to calculate human age:

Calendar age

That is, full age or full age-the age calculated according to the calendar after birth, also known as full age, is the most commonly used method to calculate age, which is simple and easy to master, and is also an objective record that is independent of human will.

Biological age

(Life span) namely physiological age: this is the age calculated according to the normal physiological and anatomical development state of human body, which indicates the actual aging degree of individual tissue structure and physiological function, and can be used to predict the future health status of individuals and estimate their life span. If a person is 60 years old, his biological age may be 60, 50 or 70.

psychological age

It is a term in psychological "intelligence test", which refers to measuring the intelligence level of human body according to the results measured by standardized intelligence test scale, and comparing the psychological age with the calendar age, we can see the absolute level of intelligence.

Psychological age refers to the age characteristics revealed by people's overall psychological characteristics, which are not completely consistent with the actual age. A person's life goes through eight psychological periods, namely, fetus, lactation, infancy, school age, adolescence, adolescence, middle age and old age. Each psychological age has different psychological characteristics, such as innocence and liveliness in early childhood; Puberty, self-awareness, physical and mental leap, psychological activities into a period of intense turmoil; In old age, psychological activities tend to be mature and stable, mature and prudent, the elasticity of physical and mental functions declines, and emotions tend to be melancholy and suspicious. The self-test table is a scale to test everyone's psychological age.

relative age

That is, the relative effective age (life span) of soul medicine refers to the time and space occupied by various life activities (including spiritual activities) which are different from other creatures (mainly animals), dominated by the highest soul, conform to the ethical norms of human society, and are conducive to the benign development of nature and society.

It can be seen that the time and space occupied by all human life activities, including spiritual activities, which are dominated by the highest soul, conform to the ethical norms of human society and are conducive to the benign development of natural society, is the relative effective age (life span) of human beings. On the contrary, it is invalid age (life span), or even negative age (life span).

Therefore, the calculation method of human's relative effective age (life span) should be that the relative age (life span) is equal to the actual age (life span) plus or minus the times that exceed or fall below the average annual labor amount of ordinary people at the same level or create material and spiritual wealth every year.

It can be seen that if a person is diligent and efficient, and his personal workload is equivalent to several people, dozens of people, hundreds of people, or even thousands of people, then his life span will be greatly extended and his age will be greatly increased compared with that of ordinary people at the same level.

As for criminals such as murder and arson, theft and robbery, hooliganism, poisoning and rape, and people suffering from ethical and social diseases discussed in Soul Medicine, their effective age (life span) should be short or even negative, which is short as a concept of human beings, and even not human beings.
