Common misconceptions that threaten your health

Which part of the body is damaged? Eyes, spine and neck skin. When studying in bedding, observe the following: Do not close the book very close to your eyes. Do not bend your back and do not drop your neck. Do not study when you lie in your arms. In this case, your distance to the book is constantly changing, and the eyes are forced to do more. Do not study when you are sleeping on your abdomen. This will damage your pillbox.
