After you blow your nose, do you look in the tissue?
Edit: I had someone comment one time when I did, and it was kind of weird and embarrassing? But it seemed like a fairly normal thing to do, so I thought I'd ask.
I judge the color to be sure I'm not getting sick and it's just a regular need to blow my nose.
I check for the presence of any blood, since I work around materials and in environments that can cause alot of dry air, giving me a higher incidence of nose bleeds.
My work environments are very dusty, and if Inhave alot of black or grey dust when I blow my nose, I know I need to clean my airways when I get the chance so the dust isn't in there longer then a day.
