Is wika answers 100 percent sure these answers are right?
There's no guarantee. The answering process on this site is
completely voluntary ...
anybody can post an answer to any question.
There's always a chance that somebody may notice a wrong answer
and fix it, but there's
no guarantee. You have no way of knowing for sure who posted the
answer, and whether
or not his answer is correct.
That's why I get so burned up when I see people looking here for
their medical advice.
