Abstract Gauge to Gauge Abstractness

If there is a gauge to quantify how much a human being contains patience, trust, stoicism, strength, tolerance, bravery, boldness, candidness, zeal, etc; basically any abstract expression or act; if there is a gauge to all that and more, it is love. A meter to measure the entities no other instrument can; an ordinal scale with an absolute zero; that is love. So underrated in that aspect. Heart rate, respiration rate, and such physiological signs are the aftermath; not a co-process; and mere signs alone, non-specific. Unfortunately, the units of measurements in love are acts, be they words or doings. "I love you", for example, is probably one of those with high standard deviations and errors. Standing by, supporting and such, on the other hand are high up on the accuracy levels, with very less possibilities of error and greater correlations. So you see, it is not the most valid tool. Yes there could be false positives but then there is no other tool yet that breaks through scientific norms to gauge all that abstractness, is there?
