Middle-aged, older, middle-aged silly? How is the age group designation divided?

Middle-aged, middle-aged, elderly this several designations we must often hear, that the three age groups specifically how to divide it? Middle-aged is how old, middle-aged is how old, old age is how old, today we will take you to understand this problem, to see the three age group designation in the end is how to divide?

1, the usual international segmentation: the international 0 - 14 years old is called the juvenile population, 15 - 64 years old is called the prime of life, 65 years old and above is called the elderly population, which 15 - 24 years old age group of people are also called the elderly population, which 15 - 24 years old age group of people are also called the elderly population.

2. The World Health Organization divides the age groups: below 44 years old for the youth, 45 to 59 years old for the middle-aged, 60 years old and above can be called the elderly, in the elderly this age group is subdivided, 60 - 74 years old is called the young elderly, 75 - 89 years old for the elderly, 75 - 89 years old for the elderly, and the elderly is called the elderly population. ---89 years old is the elderly, and 90 years old and above is the long-lived elderly.

3, China's traditional division: we can actually be divided into five age groups, 29 years of age belongs to the youth, 30 - 39 years of age belongs to the young, 40 - 49 years of age belongs to the middle-aged, 50 - 60 years of age belongs to the middle-aged, 50 - 60 years of age belongs to the middle-aged. -60 years old belongs to the middle-aged, and above 60 years old can be called the elderly.

I think there is some truth in this age segmentation of ours, the peak of national athletes is usually around 20 years old, and many athletes retire at around 28 years old, only a smaller number of national athletes are able to retire after the age of 30, in fact, the retirement age of athletes can be a very good indication of the Chinese people's physical function, after 30 years old, they start to step into the next age, no longer having the most The most important thing is that they are not in their best condition.

People over 40 will obviously feel their physical condition relative to the previous years, the physical quality of the decline is very strong, some women in 45 years old on the phenomenon of menopause, which also indicates that their physical quality of the rapid decline.

Retirement at the age of 60 is also a good indication of the beginning of the elderly stage, into the elderly stage after the serious loss of labor, so retirement is allowed.
