Talithia Williams: Own your body's data

I'll admit I am also a 'data geek' although I did not get my degree in statistics. Talithia Williams gets into how she captures her data and how she uses it. I learned how the body temperature can vary and with good reason.

The new breed of high-tech self-monitors (measuring heartrate, sleep, steps per day) might seem targeted at competitive athletes. But Talithia Williams, a statistician, makes a compelling case that all of us should be measuring and recording simple data about our bodies every day — because our own data can reveal much more than even our doctors may know.
