A System Planned in Its Every Detail

Breathing, eating, walking, etc, are very natural human functions. But most people do not think about how these basic actions take place. For example, when you eat a fruit, you do not contemplate on how it will be made useful to your body. The only thing on your mind is eating a satisfying meal; at the same time, your body is involved in extremely detailed processes unimaginable to you in order to make this meal a health-giving thing.
