Yes, the question was serious and I'm glad I received serious, mature, thought-out and professional answers from fellow nurses, as there were some replies that validated my curiosity.
The nursing profession is for curious individuals, and if you can't handle curious questions, then don't bother with the answer, especially if its going to involve sarcasm, which the SERIOUS nursing profession has no room for. Thank you for your response. In the future, you may elaborate on any of my curiosities only if LOVE accompanies, otherwise please keep it moving. Be blessed and Happy Nursing :-).
