Safety is a word with broad connotations and implies protection, shelter, well-being and freedom from danger. it is motivated by Survival, the first instinct. That is why we look right and left when crossing the road, or feel fear or insecurity walking down a dark alley or even in a relationship. Consciously or sub-consciously we want to stay alive.
This wanting to hold on to life is experienced even in a hospital setting. We feel this in major disasters like fire or earthquake's, when bombs go of, etc ...
Security is far superior to privacy. Some of us are happy talking about the numerous men or women in our lives, our ill health and even medical records, and again, even if these things became known, they may not immediately threaten our lives. Still, like all things in life, there is always a connection. I may not tell you that someone I am dating have HIV (privacy), but I will probably wear a condom. Why? Because I do not wish to die (survival) I may not give you my address or tell you how many computers I have at home.
Actually, I do not fear theft. I fear the loss and the implications in a financial sense or a potential attack on my person. I am used to warmth, shelter, food, security and a warm environment, things that are all necessary to life. Ultimately, all we do spring from an effort either conscious or non-conscious, to say alive. Survival (security) s the instinct. Privacy is related but much lower down this necessary ladder. The next instinct is the sexual one, although privacy is present there also. Security and privacy are related, but security is far superior. Survival is an innate instinct, privacy is a mental concept acquired as we grow up. Children do not think of this.
