According to my friend who is a vet, only two humans have lived with rabies and both are pretty much brain dead. I don't know how accurate that is but that is what he learned in vet school, he has been out 2 years. If you are concerned get the shots. He had them for vet school and did get sick but hey sick is better than death.

I don't think you need to be completely freaked out but you can err on the side of caution.

On a side note, I watched a documentary about humans fear response. It said it is actually a deep rooted response from our ancestors who know the things we fear are dangerous. Hey, I hate snakes and will have a response to any snake. Not a bad thing if you live in rattlesnake country. I know what to do and I am hoping to never have to face one.
