Dust

Should I say we do not know what dust does or we do, but we just nonchalant about it. I believe the effect of dust to man is obviously clear yet we neglect it, because we do not care until dust has inflicted us with one of its infections. A dusty environment can cause carter, sneezing, even cough as the case may be. A dusty environment can be easily noticed but one will need to pay a little more attention to the fans to tell it is dusty as that is the fastest means of getting carter, you think your fan is helping you get chilled little do you know it is what gave you Carter/running nose.
Let us endeavor to clean our fans always
