If you prefer to pray in your car while commuting, do you close your eyes? Just asking.
People do cry with their eyes open, but if the emotion is too great, the weeper may wish to shut out the world. However, if you weep when something touching occurs, you too may close your eyes to savor the moment.
Moving along, why do we clamp our eyes shut when we sneeze? It is an involuntary reflex similar to when the doctor taps your knee with that mini tomahawk hammer. If the doctor suddenly finds himself across the room and on his butt, then your reflexes are good.
Granted, it is difficult to keep your eyes open during a sneeze. Mind you, it is possible, but you really have to concentrate to keep those peepers open. Since sneezing is a way for the body to expel nasties from the nasal passages, some speculate that your eyes close to keep the gunk from flying into them. But unless gale force winds are blowing in your face, the expelled gooey nasal content is not going to come to a screeching halt, make a U-turn and fly into your eyes.
Now when it comes to kissing, some people keep their eyes open while others close them. Swept away by the passion a kiss can evoke, the world disappears and your eyes tend to flutter shut. Of course, if you have trust issues concerning the person with whom you have locked lips, you may want to keep your eyes open. Otherwise, he or she may steal your wallet.
Our discussion cannot omit all the blinking we do. Opinions vary on the estimated number of times a person blinks per minute. The number ranges between 16 to 30 times per minute. So, if you are awake 16 hours a day that equals 15360 blinks per day and 5,606,400 per year.
