The video is about 41-year-old Bob Troia, who keeps track and quantifies pretty much every detail of his daily life. Bob Troia sleeps with a gadget on his head that can give information so detailed that he can see when and how long he was in a deep sleep, rem sleep, and light sleep. All throughout the day, Troia can look at his phone and see how stressed he is, based on his heart rate, sweat levels, and skin temperature. Troia explains that he has an elevated risk of type 2 diabetes and by taking his blood pressure and his glucose levels every morning, he can keep the diabetes at bay and the stress levels in check. The narrator explains that all Troia’s data is stored in a computer program, his phone or on a spreadsheet. David Pogue who is a host of NOVA scienceNOW says that self-quantifiers range from the average person who is just trying to lose weight, to the more extreme like Troia. According to Pogue, these wearable devices can be motivators and raise awareness of one’s activity levels which will lead the user to do more activity. Pogue explains that many devices allow you to share your results, which seems very appealing to many users because of their narcissistic instinct.
