Personal informatics

For the truly compulsive, from an article in The Wall Street Journal, there's a new trend involving keeping tabs of every little thing we do. "Everyone creates data--every smile, conversation and car ride is a potential datapoint. These quotidian aggragators believe that the compilation of our daily activities can reveal the secret patterns that govern the way we live."

I am kind of compulsive, but this is not for me. Sounds very stressful frankly!
