Dear, "Josh", before you make an assumption that the nurse who more thoroughly answered this question than you has some mediocre associates degree, look up the curriculum for nursing school, you will notice that it includes microbiology, general biology, pathology, chemistry, (insert much longer list of difficult subject requirements). In addition (from actually communicating with her) she has many years of experience, and from what I've seen, it's nearly impossible to not be condescending towards some nearly all of the individuals who answer the questions in the health section yet have the intelligence of a troglodyte (go look it up the meaning). And before you try to say that you had no way of knowing if she's intelligent or not, look at her answers to other questions, her profile is public.
Also, I hardly think putting "I'm a nurse." under the references section counts as flaunting off her education, her knowledge of pathology comes from her education, and therefor it is warranted and even necessary to put her profession to distinguish herself from obtuse users (such as yourself).
As a final word, there is no need to traduce and individual who calls out a flaw in your answer, you should thank her for correcting your error. I gave your answer a thumbs down by the way, no need to reward an answer that a child could have postulated.
I'm a high school student.
