10 psychological facts about man and woman

Here are the top 10 psychological facts about man and woman that people don't know

10. Men typically have thicker skin—by about 25 percent. They also have higher densities of the protein collagen.

09. The differences in density goes beyond skin deep. Usually, men also have denser, stronger bones, tendons, and ligaments than women.

08. From about age 14 to 51, women typically need more iron than men. This is due to their loss of blood during menstruation, which typically happens in a cycle of 28 to 40 days.

07. On average, men typically have more muscle mass than women. And those skeletal muscles are faster and more powerful. But women’s muscles more readily resist fatigue and are faster to recover.

06. The second-longest finger for most women is next to their thumb—the index finger. But men are the opposite. They usually have ring fingers—those next to their pinkie finger—that are longer than their index fingers.

05. Folate is an essential vitamin. So, men and women both need it. But it’s especially crucial for women of child-bearing age.

If they become pregnant, women need enough folate to support the neural development of their babies.

04. A woman’s circadian rhythm is more likely to be short of a 24-hour period. (They’re often six minutes short of a full day.) Men are more likely to be night owls. But women function better during periods of sleep deprivation.

03. The daily calorie requirement for men is higher than for women. There are a few reasons for this: higher muscle mass, stature, and basal metabolic rate. Pound for pound, muscles burn more than double the calories fat does.

02. Men and women carry different amounts of body fat. The higher body fat in women—about 10 percent—mostly supports reproductive physiology. One example is when a woman’s body fat gets too low, she stops menstruating.

01. Women typically carry their body fat in their hips and thighs. Fat tends to deposit around men’s stomachs.

***The difference between men's and women’s size, muscle mass, and calorie needs means men typically require diets higher in protein.**
