What are the differences between men and women?
The British “Daily Mail” December article invited British and American experts to summarize the “13 hidden differences between men and women.”
1.Women have better ability to distinguish colors Andrew Rotary, professor of ophthalmology at the University of Southampton in the United Kingdom, said that women have more “color vision” genes in their eyes than men, which makes them more capable of identifying different colors.
Men’s bones are stronger. Paul Allen, an orthopaedic specialist in Kent, UK, says that the outer layers of men’s bones are thicker than women’s, causing fractures.
Male bones are large and female pelvic cavity is small, but the size of the bone opening at the lower end of the pelvic cavity is convenient for having children.
3．Men’s nose diameter Men’s noses are on average 10% larger than women’s because men have more muscle groups and need to inhale more oxygen.
4．Men’s liver cancer David Royd, an expert in liver surgery at the General Hospital of Leset, UK, said that women’s livers are smaller than men’s, so they are used to replace alcohol dehydrogenase and drunken alternatives.
5.Women’s hearts are small, and their heart rate is slow Dr. Green Thomas, an expert from the Bristol Heart Institute, said that women’s hearts are about two-thirds of men’s; men and women have an average heartbeat of 80 and 72 beats per minute; women with AF have a risk of strokeThan male sex.
6.Women are relatively relative Although women are smaller than men, they are both the same length.
Therefore, with the same amount of food, women are more likely to feel full.
7.Dr. Rocht Lal, a London lung cancer expert on women’s lung load, said women’s lung capacity is 30% smaller than men’s, and the airways are narrowed, which reduces lung load.
8.Women are more flexible. Professor Alan Hillman, an expert at the British Arthritis Institute, said that women’s ligaments are looser and easier to stretch, and it is less difficult to complete the splits.
9.Women’s urinary tract is shorter Christopher Eden, a urologist at the Royal Surrey Hospital in the United Kingdom, said that women’s urethra is only 3 cm on average and men’s 20 cm.
Therefore, women are more likely to develop urinary tract infections.
10．Men’s beer belly, women’s buttocks, thick legs, men’s fat are often lightly accumulated on the waist, while women easily accumulate on the chest and thighs.
11.After menopause, women’s voices become thicker. After women’s menopause, estrogen decreases and the vocal cords swell, so the voice becomes a bit heavy.
12.Women’s skin is thinner Dr. Sagad Rajippa, an expert in dermatology at Birmingham, UK, says women’s skin is thinner and therefore more prone to wrinkles.
Men have a higher ratio of dermal protein to skin, which makes them look younger.
13.Women’s immune system is more active. Women’s immune system is more active, and their ability to cope with infection is stronger. After infection, the body is injured less than men.
Women’s immune system ages more slowly, which results in longer life.
