I must say that some of the responses here gave me a smile and some made me say to myself "What?". When I was instructing the few people that I did. I taught them that biting in any form or fashion was not only acceptable, but requiired and your fighting for your life, so anything goes right up front, not after they have you under control. The chance of contacting aids through that method is slim and they have drugs to help fight it, if it should happen by some odd chance. We also need to during our training expel all the myths surround acquiring aids and teach/instruct our folks that their life at that moment is more important then worrying about some myth down the road. Here and now during a life threatening situation is what is important, not what might happen years down the road. Just my view on it.
