I’m forever blowing my nose. It doesn’t matter if it’s summer. winter, hot, cold, whatever. What the hell’s wrong with me?
Also, what do you reckon, is it better to blow or sniff?
Me too! I thought I was the only one 
What’s that running down your lip?
You may think it’s funny but it’s not.
Things could be worse.
You could be full of shit.
Have you been tested for allergies?
Personally, I prefer to blow my nose rather than to run snot past my taste buds before I get rid of it.
Blow or sniff (snork)? The mucus itself is your own, and it won’t hurt you a bit; however…your nose is your body’s air filter, and you’ll be swallowing all the dust and pollution your nose tried to save you from. On top of that, you’ll be swallowing air along with the snot. The air will probably exit as farts. It’s your call.
Better the air than the mucus.
OH dear, a case of “I’m forever blowing Bubbles”. Isn’t there a well-known entertainer who might have the same affliction.
OK, I seem to blow my nose a lot too, but I think in my case, it is not always necessary - more a sort of nervous tic, or one of those things like checking for my keys many many times before I go out.
If you are actually needing to blow/sniff more often than most, sounds like a good thing to ask a doc or nurse about.
But it *could8 be a useful trick to get you more personal space on public transport, of course.
