ABSTRACT
The human body has the unique and wonderful ability to heal itself. All of us have had minor cuts or scrapes that healed within a matter of days and have long been forgotten because they left no visible trace. We all have fallen victim to common infections and viruses, which our bodies have gone on to fight and eventually overcome successfully. Other damage to the body can be more severe, with wounds that are too deep or pronounced to heal without a scar. Some damage cannot be repaired, and we may feel its effects for the rest of our lives.
