Excerpt from an auto-analytics reality check
Like many "self-quanters," Smarr wears a Fitbit to count his every step, a Zeo to track his sleep patterns, and a Polar WearLink that lets him regulate his maximum heart rate during exercise. He paid 23andMe to analyze his DNA for disease susceptibility. He regularly uses a service provided by Your Future Health to have blood and stool samples analyzed for biochemicals that most interest him. But a critical skill separates Smarr from the growing pack of digitized patients who show up at the doctor's office with megabytes of their own biofluctuations: he has an extraordinary ability to fish signal from noise in complex data sets.
