Often, I do. Sometimes I respond with a, "You are so good looking!"

I always say god bless you, just as I day please and thank you. It's more about manners for me than about whether or not there is a god to bless you.

I like the word "bless." It’s one of the few words I know that “confer prosperity or happiness upon someone.” I am aware of the religious implications, but like the etymology of so many words, meanings have changed over time. Language is a living entity, and some of these words evoke our better angels. That makes them worth using.

I say it because it is a socially accepted behavior, and I view it is a secular adaptation of something that historically started as a religious practice.

I do not say anything. I have to admit though, it feels a little rude.

I say 'bless you' cuz I can never remember how to say 'gesundheit' lol! To me it's also like saying 'merry christmas' and 'happy easter'. These are religious holidays but I was raised to see them as just holidays. Occasions. Saying 'bless you' to me is also like when someone says 'excuse me' and I say 'sure' or 'of course' or 'you're excused'. Manors are important to me. I also say 'thank gawd'. It's just figure of speach to me.

I say gesundheit. Bless you was a hard habit to break, but I dropped the use of it a few years ago.

My grandmother always said "keep the change" when someone sneezed and I have always said it which usually gets a good laugh.

yes

I find that question funny because saying bless you has always been so automatic! It's weird how so many things in our lives are just rote.

Yep, it's habit. I don't care about the religious connotations.
