Well, blowing the nose, turns out, may actually cause mucus to be propelled back into the sinus cavities.
That’s not a good thing in general, and if you’ve ever felt it happen, it can be quite uncomfortable.
Plus it seems like there’s really not to be had with blowing… you can blow a hole in the tissue, ricochet nastiness back onto your face, etc.
OTOH, picking is just nasty… gotta be in a bathroom with some good soap right at hand, and even then it’s not really sanitary.
Ugh.
Anyone got a third option?
