185.WHY DO WE WALK IN CIRCLES WHEN WE ARE LOST?
Here’s a sure way to win a bet! Challenge anybody you know to walk blindfolded straight down the sidewalk without going off the edge. He is sure to lose because he’ll soon start walking in a circle!
People who have been lost in a fog or in a snowstorm, have often walked for hours imagining they were heading in a straight direction. After a while, they arrived right back where they started from.
184.WHY ARE SOME PEOPLE AFRAID OF HEIGHTS?
As human beings, we are subject not only to physical pain, but also to emotional pain. A situation may cause us great emotional distress. Sometimes we deal with this quite simply. For example, we may cry, or blush, or break out in a sweat.
But sometimes, when the emotional stress is greater, or our power of resistance is weaker, we may develop other reactions for dealing with this pain. One such way is called a phobic reaction.
183.WHAT IS THE PULSE?
You have probably had your pulse taken hundreds of times. And it’s quite a simple thing for you to take your own pulse or someone else’s. When a nurse or doctor does it, the patient is sitting or lying down. The arm is placed in a relaxed position with the thumb turned upward. With the index finger, the nurse finds the pulse beat on the wrist near the thumb side of the hand. The beats are counted for one minute.
