To tell you the truth, I was afraid as well! I was hypnotising my saliva while making the test;) real fear to know the truth! I am sure you are ok, dear!
and no, I know little, but I study and read a lot to know more;) so it's just reading, I am not a genius;)
and I wonder why nobody told us these small secrets when we studied at school, so many subjects but we don't know simple rules how to be healthy;(
healthy people don't bring profit, so there is no need in them..
