To know better

In my youth (I can now say it without dispute, seeing how all the cashiers at most store I shop at are no longer within an age range that I can comfortably hit on them as I make my purchases, but that's another topic...) I attended college for two and a half years (pre-uni for those unfamiliar with Quebec's education system) and focused my studies on various science disciplined: maths, chemistry, physics and biology, all of which were preparatory courses for university, so nothing extremely comprehensive, but were insightful none-the-less regarding modern science and modern society, basically, how shit works... My favorite topic was unequivocally biology, having chosen to broaden my knowledge on the subject with two microbiology courses, fascinating material really, enough so that I'd actually look forward to go to my classes and even showed up, on time, without hangovers (well, most of the time), which was definitely more attention than the mathematics teacher got out of me, poor lass, what ungrateful bastards we were then, oblivious to the fact that she dedicated years of learning for the purpose of affording us the chance to become knowledgeable,oh well...
Something is to be said from all those hours spent on school benches, I may have chosen since not to follow through the unwritten expectation that I would choose a career and pursue the betterment of society over my own, but I haven't disregarded everything, I still retain  most of what I learned. I still hold this same fascination I always did for the works of this universe and especially for the human body, its intricate processes, which is why I always imagine some ailment afflicting me, not quite a hypochondriac, just a little more worried than I ought to be... I also avoid or put off going to the doctor as much as I can, since these are always just worries and nothing more, so long as there isn't a diagnosis, because if there were, there's this off chance that it might become real...
So I'm sat here typing this, three days after being told by a dear friend who visited me that she had developed strep throat, an infection with serious enough repercussion that I worry a little. I'll go tomorrow...
