Quantified self means Quantified self
The Quantified self (or QS) movement is the trend to keep a lot of things over and out of yourself. With the emergence of wearables and gadgets, it's always easier to keep track of everyday things: How many steps have you put, at which locations you've been, what did you eat, what did you drink, etc. The idea of QS is that through all this information you can learn more about yourself, learning from it. By comparing with previous days you can see if there is improvement, and by comparing with others there can be some kind of competition. YouTube FESv2CgyJag [/youtube]
