I own a fitbit watch, a Motiv ring, a withings scale, a withings blood pressure cuff, a Thermo thermometer. ABSTRACT. All of my personal fitness trackers generate low variability data series. When a data series doesn't change day to day, there is no information to react to, at least in the short run. These data series are driven by other low variability series, name my lifestyle (what my various, slow to change habits are). Only the HR monitor has a good deal of daily variability, which is mostly only useful if you are actively training for a race or something.

Lets just get people knee jerk reactions out of the way: - Being poor isn't just eating too little, it also means being low on human ca...
