People's bodies usually only grow to 165 centimeters. Regardless of whether it is a man or a woman, if you don't have such a height, you either don't eat well or rarely move outside. There are few congenital causes that affect height, and even fewer genetic influences. Therefore, children are usually born with a height of about 25 centimeters. Each 7 centimeters is one year, and a 20-year-old is 165 centimeters. This calculation method becomes scientific and accurate based on specific standards of space, nutrients, food, food intake, etc. There will not be much difference between longevity and early death in this world. The average life span of people in that era was 134.2713 Years. The difference between this year and the earth's 137 years is only one decimal point.
Height and life span can be calculated accurately, and similarly, the physical development of men and women can be calculated equally. Men and women who are 20 years older are adults. At this time, the girl's breasts are upright and the diameter is 6.2 Cm. Similar to our A cup. Men's genitals are also similar. The diameter of an adult male's genitals is 4.5 Centimeters and 6.3 Centimeters during sex.
If this understanding were based on popular science, no one in the world would be scientifically illiterate.
