New Mars Forums

I've got a question for discussion:
Let me first say I'm all for not only going to Mars, but establishing a permanent human settlement on the red planet. 
That said here is the Q- If we accept the idea that life did/ does exist on Mars, should we not consider the idea that simple life forms, say comparable to germs on our planet could also exist there?
Is it not possible that while exploring and reviving the Martian surface it might be possible to bring a microscopic biological threat out of hibernation?
Lets just say that if we aren't going check out such a threat , I would insist on NASA sending a large supply of aspirin along on the trip as well.
