I am a First Responder and trainer and teach my guys one simple rule, if it's wet and not yours, don't touch it...Before anything comes in contact with yourself, put on rubber gloves and keep a pair in your first aid kit. Two things can happen if you don't put them on, if you come in contact with someone that has a disease, you now have it. Secondly, if you have any bacteria's on you, you have now infected that person and both of you will need treatment. Just some food for thought.
