The concept of saving is not as simple as it might appear. Saving will often involve a choice or dilemma that presents a subject or object to be saved.
However, to understand what must be saved, an understanding and analysis of the underlying problem needs to be undertaken. Meaning, saving cannot happen instantaneously. Thinking, planning and implementing a solution to save something must happen.
Even the thinking process is an expenditure of time, another asset that someone might try to save.
