I find the statement that “we live in a crazy world” to be an understatement of the reality we live in. So many things can and go wrong without any warnings; from terrorist attacks, suicide bombers to shootings in schools.
In all this madness, there is a universal language that can and helps a lot of people (if not all) cope with all the madness of the world. Music is its name. Humming melodies have been known to help people work harder and even to calm themselves while in the face of danger.
Music might be a simple act but it is very powerful. This is something that has been proven even scientifically for “Ye of little faith”
