To answer Sara's question and get you all of the edge of your seats, hot tubs are fine to use if they are your own private hot tub and not the one at the YMCA. Or, if you are on vacation and you are desperate to be warm, then it is ok to use the hot tub as long as you do not make eye contact with any of the other gross strangers sharing the hot tub with you. It is smart to bring your own bottle of bleach and chlorine though. And when you get out of the hot tub, go immediately to your room and rinse off with a solution of the bleach and chlorine mixed with antibacterial soap.
