How am I wrong with technical details?

Never said they are currently tracking everyone’s biometrics? In fact, I stated in one comment that I certainly don’t believe they are.

I am aware of the common correlation between heart and respiratory rate. However, trying to use one to determine the other is not always reliable. As well, not everybody has a respiratory sinus arrhythmia, though it is very common. Thus it is not always a perfect way to determine respiration, and other methods may be required.

Also, I was trying to show the most advanced method, which was relevant because it came directly through DARPA, which was the sponsor of lifelog.
