A Metric System on Emotions

There should be a legal limit for love, say just above 80 mg/dL which is the legal minimum of alcohol--- enough to be labelled drunk and disorderly. I don't know if such a thing is possible, or someone could invent an analyzer to measure the normal range of love as an emotion, or if a scientific probablity exists which might someday make it practical, I really don't know. All I know are first-hand experiences: instances when during psychiatric rounds, in an alarming regularity that approaches a level of significance, cases like addiction, suicidal tendencies, narcissistic rage leading to God -knows -what all points to a certain inadequacies that point insanity as the effect, not the cause--- and most spring from emotions of being unloved: traumatic relationships, family members not paying much attention, or as trivial as a forgotten bday gift. Somehow, if we are able to measure in a definitive, metric range an emotion such as love, perhaps it would open the floodgates for better diagnostic techniques to prevent irrational behaviour, or for pharmaceutical companies to manufacture drugs that would maintain "love-levels" in each of us; or perhaps aid the growing science of Genetics and once and for all establish the role of love, in an evolutionary scale, in the advancement of our species. Insane? I know, that's why it's cool.

You know how a woman feels when she holds her baby for the first time, someone described it as if her whole soul would explode. Now that's unheard of, and dangerous. Souls exploding is the first sign of insanity, especially if that baby grows and throws you out to nursing homes. Teenagers with all their raging hormones often commit mistakes in relationships, leading to endless tears and a broken heart--- Oh yeah, a broken heart is just a ledge away from suicidal behaviour. Is there some thing one can do? Ever heard of heroes dying for their LOVE of their country? That's just plain crazy.

It's a fact of life, controlled emotions eventually explode, gnashing uncontrollably out of you like in those Alien movies. Love more so. That's why they're called emotions--- which in ancient Greek means "cannot be controlled by motion". Ok that one's made up, but it serves the idea. It makes us do things, good or bad, and the better it is the potential for self-destruction exponentially increases. Therefore, it stands to reason that given the technological sophistication of our time, we should somehow advocate, I apologize for the overkill, a metric system of measurement for emotions, most especially love. It is not a very romantic thought; and I am, in fact, a clinging Romanticist, so it hurts me deeply to push this idea further. However, looking back at all my mistakes--- decisions based on overwhelming emotions resulting to unwanted catastrophes--- the idea is not bad at all. If somehow I can find something to numb up bottled pains, control them somewhat, then perhaps it's reasonable.
