  Not all questions are in our domain of expertise, so one has to get familiar to the area and then answer.

  Hey!
  
  I’d say that the biggest challenge is not having the expertise to answer some of y’all’s questions!!
  
  However, it is important to point out that part of being a scientist involves looking for and/or understanding hoardes of information that may be outside of your expertise! That is why you see us listing sources.. to show y’all that sometimes we do not know, and that we have to find reliable answers in order to answer questions that we do not know!
