The heart is a hollow muscle that pumps blood throughout the blood vessels by repeated, rhythmic contractions. It is found in all animals with a circulatory system (including all vertebrates). [sic]
As a matter of fact, we know our heart. It is further more than that. No googling will show you enough results about what it means. There is no digital action and reaction for the abstract.
Only real feelings can build and lead a consistent heart abstract. There is no way. You will never find it, unless decide to live and face your fears, no matter how much efforts on your search.
Are you ready to take the chances? Are you prepared to build your own story? Will it drive you to a happy ending? Can you handle the consequences? What is the point of all this? Try us.
