Recognize that number? It is the number you think it is your body temperature. Well, guess what? Surprise! Your average body temperature is not (Rubor Dolor Calor Tumor) 98.6 degrees. In fact, the mean is 98.2 plus-minus 0.7 degrees. Not only that, your body temperature also depends on the time of the day. See? Things are not so simple as you think it is, and you should never categorize things in a single number or… well, category. So yeah, my five cents from me to you here is to be careful of overly simplistic facts without evidence, and if things seem a bit dubious, investigate it. Oh, and if I were you, I would be careful of the sources. Preferably, sources from experts of their fields are a good place to start.
