In the mouth-breathers' club
Davis Schwimmer has a terrible problem with mouth-breathing. Like Ted Danson, he seems to find it impossible to breathe through his nose. If you watch him on screen, you will see that even if he closes his mouth for a little while, he always has to open it eventually to breathe.
Mouth-breathing can be caused by enlarged adenoids, a deviated septum, swollen mucus membranes caused by allergies, etc. Breathing through your mouth can lead to a dry mouth, bad breath, tooth and gum decay and other problems.
Also, someone standing there with an open mouth looks really, really dorky.
Personally, I would hate to kiss Davis Schwimmer - he must have horrible bad breath.
My question is, why on earth doesn't he do something about it? There are surgical and medical treatments that would fix the problem and give him great relief, allowing him to breathe freely and easily through his nose (and keep his mouth shut!).
PLEASE, DAVID, GET IT FIXED!
