Today technology is present in almost every aspect of our lives. We communicate through e-mails, text messages, and social sites. We watch television and movies and play video games for entertainment. There is almost an app for every part of our lives, from GPS to weight watching. All of our activities can now be tracked and turn into tons of raw data. This data is highly sought after by companies who watch popular trends to determine the best promotion of their products. Some governments are starting to use technology tracking and data collecting techniques to track down wanted criminals and terrorists. However, there is more to quantification than other people collecting data about you. Many people are now using technology to keep track of their daily activities such as sleeping, running, calorie intake and spending. This self-tracking can be done either passively by using special gadgets or smartphone apps or actively by creating charts on a personal computer.
