BREATHING
To keep your body straight, many pieces of information derived from billions of receptors in your leg muscles, feet, back, abdomen, chest and neck are evaluated and a similar number of commands are given to the muscles each second.

We do not spend any extra effort to speak. Man never plans how far apart the vocal cords should be, how often they should vibrate, in which sequence, how often and which of the hundreds of muscles in mouth, tongue and throat should be contracted and relaxed.

Nor does he calculate how many cubic centimetre of air should be inhaled into the lungs, and how fast and in which frequency this air should be exhaled. We could not do this even if we wanted to! Even a single word uttered from the mouth, is an outcome of the collective working of many systems stretching from man’s respiratory system to the nervous system, from the muscles to the bones.

SUBHAANALLAH!!!
