On January 18, Yahoo News reported that public data from the Japanese Ministry of Education, Culture, Sports, Science and Technology showed that the average height of 17-year-old men in Japan was 160.6 cm in 1948, which increased to 170.9 cm in 1994 and dropped to 170.8 cm in 2021. According to expert research at Japan's National Growth and Development Medical Center, the main reason may be the increase in the number of newborns with a birth weight of less than or equal to 2500 grams. With the advancement of science and technology, women can independently choose the date of delivery, give birth in advance or deliberately control diet, which affects the birth weight of newborns, and then affects the height of adults. Shengqi said that after ten years, the height of Japanese people may continue to decrease, and men may be shorter than about two centimeters, but the Japanese man with a height of 168 centimeters said, I will not be entangled in the problem of height, the most important thing is to have confidence!
Doesn't it mean that the average height of Japanese people is already over Chinese? Didn't they already borrow from Europe and the United States to change genes for the height of their offspring? How can it be short again?
