1. Women have a wider-ranging peripheral vision than men: This allows them to check men out from head to toe without even getting caught.

Men, however, because of a relatively poorer peripheral vision check women out in a very obvious way, moving their gaze up and down.

In other words, men don’t “ogle” more than women do; it’s just that their tunnel vision makes it easier for them to get caught easily.

2. Humans use body language in three major ways: As the conscious replacement for speech, as the mirror or betrayer of our mood, and to reinforce our speech.

3. The largest bone in your body is known as the femur which can support thirty times the weight of the human body.

4. Your little finger is responsible for over 50% of your hand’s strength.

5. Your skeleton renews itself completely every ten years.

6. Your body can detect taste faster than the blink of an eye. It happens in only .0015 seconds.

7. We don’t use only 10% of our brain. In fact, humans use almost every part of their brains almost all the time. Even when we are sleeping, every part of the brain keeps showing some level of activity.

8. Aristotle, a Greek philosopher, believed that our emotions originated from our hearts rather than from our brains.

9. Figurative language-wise, the popular saying “taking the bull by the horns” stems from a Greek myth of Heracles who saved Crete from the raging bull by seizing its horns.

10. Alfred Adler was the first theorist who suggested that birth order may affect human psychology.

He argued that a firstborn child is “dethroned” by a second child, which then permanently affects the personality of a firstborn.

Additionally, younger and older children can be pampered and spoiled, permanently affecting their later personalities.
