Firstly, as a human being it would be reasonable for other human beings to assume that I eat, drink, sleep, have sex, pick my nose, break wind, etc. If these activities are conducted within the bounds of acceptable social behaviour then i should have no concerns that these activities are credited to me. So, if I conduct my life in a manner which does not jeopardise the safety, welfare or comfort of others, and which is within the bounds of the laws of the land then it matters not what others know of me.
I only require privacy in the sense that some special things I prefer to enjoy without an audience, and sometimes i prefer to be alone.
The 2 most significant privacy issues would then relate to my financial affairs and my identity. I would not want these stolen or abused.
Cheers,
Max King
