Technology is undoubtidly changing the world in ways people couldn't have imagined even just 10 years ago. 

We tend to portray ourselves better online than we do in real life which is what the TedTalk spoke about. I think this is because we all either consciously or subconsciously know that anyone can stumble upon what we put out onto the internet and want to make a good first impression. I think we've become so obssessed with how we appear to others online that it's spilled into our real lives as well. People will track how far they've run, calories, heart rate, sleep, etc. I see more and more people tracking their stats either on a phone, watch, or some other device. They want to know as much as they can about ourselves so we can build a better self image. 

I don't personally wear a FitBit or anything like that because well, A. I can't afford one and B. I don't feel the need to know every little detail about myself. Knowing whether I walked 1,000 or 10,000 steps doesn't cocern me because I have the privilege of being in good physical health and don't think about things like that. I think if I did start using a device like a FitBit, I would get overly obessesive to the point of becoming more mentally unhealthy than physcially unhealthy. 

I'm not too concerned about the privacy factor because while I do think privacy is important, I don't have anything to hide and I'm just one of billions of people on this planet so the chances of me being singled out for a piece of data is slim, but not 0.  There's definitely a line to be drawn when it comes to privacy, but I'm not quite sure where it is.
