How to hack a human?
For most of the people above question can be funny. But in our real life it's is not funny. In our day to day life we hack the systems of the other people. But unlike hacking computers, which require various technical skills, hacking humans may be potentiated by an affective look or a pleasant smile. Suppose that you want to marry some one. First you have to hack your partners system and gain access to it. Then you can create a permanent data link. Only after that your partner will love you. So what do you think about this. Your comments are welcome.
