Hi. I'm new to mothering.com, and I was very happy to discover this tribe.
As for sneezing, I've never understood why it's necessary to say anything at all when somebody sneezes. If I do say anything, I say "gesundheit", but even that feels odd and seems fairly pointless to me.
I loved Religulous. I'm currently reading The God Delusion by Richard Dawkins, and I highly recommend it.
As for sneezing, the translation of Gesundheit or Salud, simply means to your health, or something like that, which simply means you hope that person's sneeze is not indicative of an illness. I think that's nice. My girls say gezundheit when they sneeze because they copy what I say. I say it because I want to override what other people say. My mother and strangers have said Bless You or God Bless You. One time one of my daughters said that and I just looked at her and said, what does that mean? She said, I don't know. I said, I thought we said gezundheit because it means I hope you're not sick. And that was the end of that.
