When I sneeze I usually follow up with " die you damn fool!". I've never said it to someone else. Not sure about that.

I think saying bless you is a quoculism and I spent my life saying it. I don't see it as a religious statement

"Are you going to eat that?"

I usually say "bless you" - but completely out of habit. I have been trying to correct myself into saying "Sagan be with you" (as in Carl Sagan) just to counter the religious-ness(?) of 'bless'

Gesundheit most often. Occasionally "May the Force be with you."

I believe its a cultural norm rather than a religious “blessing”.

Goes-in-tight

I just say bless you. No God included or needed. Satisfies both people's views I guess. Just like with the thread on saying grace at dinner. I'm willing to go along with the idiocy because I'm secure enough in my view on the subject while pleasing those around me. If it gives them comfort then so be it. It would be different if it's something more extreme, but I don't see the need to cause conflict with such trivial things.

"Need a tissue?"

Ancient (war time) UK Version.

Coughs and sneezes spread diseases.

How about...."What are you taking for your cold?
You acknowledge the sneeze without the religious angle.

Bless you, not from a religious context but is a saying dating from 1665 the black PLague times.
The song originated from UK namely London (RinG of Roses)

Americans say it wrong- as 'Ashes ashes we all fall down is not the original wordage'. The song is Atissue (a sneeze) the word bless you was a result of people sneezing hoping it wasn't the plague.

"Don't explode your head." From when my kids were little.

Goes in tight or cuntstight lol

some ignorant humans thought a sneeze was the soul leaving the body and it supposedly couldnt return unless the body was first cleansed with a blessing. i usually say bless you and offer that story

I say, "Bless you", and smile my conspiratory smile.

Never say bless you and find it repulsive especially near me and even worse if it's not inhibited.

Goves over a lot of peoples head gesundheit, especial where a lot of Spanish is spoken.
