Anmol Madan, cofounder of Ginger.io was able to predict with 90% accuracy when people were sick based on their cell phone use. The data he collected included texting and GPS data. Interestingly, when people are sick they don't talk on their phone as much or move around as much. Further, aggregated cell phone data can actually predict disease outbreaks.
The idea that your neural network can be completed outside of your body with other devices. So will iPhones help complete any missing circuitry you might have? I'm intrigued by this in relation to my new mobile phone application: GottaFeeling. I think there is huge potential for mobile phone applications to help people exercise circuitry that may have atrophied and even standing in for gaps in their neural makeup.
