Scientific explanation of the year of the Natal Year

Honmei year is a Chinese word, formerly known as the year of the return of the five elements and several lives, that is, the 60th year of life, which now refers to the year in which the lunar calendar genus phase is located once in the twelfth year, commonly known as the genus phase year. In Han traditional customs, the year of the Honmei is often considered an inauspicious year. The folk song "The year of this life is too old, too old to sit on the head, and there will be no joy and misfortune" is the best portrayal of the unlucky year of this life. Therefore, Han folk usually call the "Year of The Life" also known as the "Year of the Threshold", that is, spending the Year of the Life is like stepping into a threshold.

So why is this life year regarded as a "threshold"? I think it is that most people can't adapt well to the transformation of body or identity, and all kinds of incongruity causes the illusion of "sills".

One is the physical aspect. The human cell renewal cycle is generally 120-200 days (except for nerve tissue cells), about every 6-7 years to replace all new cells, the longest bone will be replaced in about 10 years or so. Children who are 12 years old, known as prepuberty, have a peak of growth, sexual characteristics begin to develop, and sexual consciousness begins to awaken. At the age of 24, growth and change basically stopped, and the body shape solidified. Around the age of 36, the body's functions began to deteriorate, and the speed of various reactions became slower... When you're 36, are you still going to play basketball the same way you did in college, or are you bound to get hurt? If you do e-sports live broadcasting, and the slow reaction force leads to a decrease in the quality of the live broadcast, will it necessarily lead to the loss of viewers? This is the "true destiny".

The second is the identity aspect. At the age of 12, I have just completed my elementary school stage and am about to face more mature interpersonal interactions. At the age of 24, you have to adapt to the transition from school to society. At the age of 36, he must undertake the main work of the unit, and at the same time face the double burden of old-age care and child-rearing. At the age of 48, there may be a risk of unemployment or marginalization, and there may be grief over the loss of a loved one. At the age of 60, you have to face the transformation of retirement, the loneliness of your children after independence, and the hardships of raising grandchildren. If you can't adjust your mentality and way of doing things in time, or use the idea of facing society in school, and use the radicalism of young people to deal with the calmness of middle-aged people, then it is foreseeable that one by one "thresholds" will also be held.

Therefore, the year of this life is "threshold", but it is also a "threshold" that can be dealt with in advance, and I hope that everyone can accurately grasp the transformation of their own body and identity, and be safe for a long time.
