Curiosity is not a bad thing. In fact, many teachers appreciate their students who ask tons of questions. And the wisest people in the entire world are those who always have a query to inquire like Albert Einstein. You might wonder how things work and why circumstances happen. Here are some of the questions often asked with corresponding answers from experts.
1. Why Do People Cry? - According to Stephen Sideroff, PhD, psychologist at Santa Monica--University of California Los Angeles & Orthopaedic Hospital and clinical director of the Moonview Treatment Center in Santa Monica, Calif, ''Crying is a natural emotional response to certain feelings, usually sadness and hurt. But then people [also] cry under other circumstances and occasions." But where do tears come from, you may ask. Roger Knaggs, professor in clinical pharmacy practice at Nottingham University explained that a person's tear ducts is linked with the part of the brain that deals with a person's emotion. "When we hurt ourselves, the tears released when we cry contain stress hormones, so you are literally crying away the stress," Knaggs stated.
2. Why Squinting helps to see things more clearly? - There are two answers to that question. First squinting changes the eye's shape keeps the light centered back into one's fovea. Fovea is a tiny part of the retina with the role to help you distinctly see things. Second, it decreases the light beams that enters the eyes. In order to have a clearer vision, the amount of light should only be few.
3. Why you can only wink with one eye? -Usually people wink with the eye which side is also where the dominant hand is located. If a person's left handed, he usually wink using the left eye. Just like in writing, where you have a dominant hand that you occasionally use, same with the eyes. The left part of the brain controls the right side of the body and the right brain hemisphere cause the left part to move.
4. Why your heart is located at the left part of your body? Since heart plays a very vital role in determining if a person is alive, you might be questioning why it isn't in the center. Dr. Rajay Narain, a research cardiologist explained, "The reason there are asymmetries in the first phase of our development is to do with evolution. As our digestive, circulatory and central nervous systems got more complex, Nature had to find ways of packing everything into our bodies. Having everything centrally located is an inefficient use of space."
5. Why do you feel cold when you're sick? According to Dr. Lindsay Nicholson, a specialist in autoimmune infections at the University of Bristol, "When we get sick and the hypothalamus detects the immune response to microbes, it then raises the body temperature, which we feel as a fever.
Hence, people get chills once there is a fever since they feel colder than the body's hot temperature.
