"If wearables were always accurate, DexaFit wouldn't be necessary."
If wearables always governed accurately, external controls verifying the reliability of their outputs wouldn't be necessary. To administer the best diet and fitness plan for your body, the great difficulty lies in this: you must first enable the wearable to govern accurately; and in the next place, trust it helps you make progress.
"If men were angels, no government would be necessary."
- James Madison
If angels were to govern men, neither external nor internal controls on government would be necessary. In framing a government which is to be administered by men over men, the great difficult lies in this: you must first enable the government to control the governed; and in the next place, oblige it to control itself."
