NSA having recordings of all your conversations in presence of your (even visually turned off) smartphone or any other electronic connected device, recordings of all your movements, all your computer activity, emails, internet browsing, video recordings of you in many locations... correlated with such recordings of other people - what else they are to know about you? They will be able to predict your tomorrow's behavior better than you, like the girl you meet and how it will go :)
