The Science of Booger Formation...Thanks to Ask Yahoo

As you're no doubt aware, boogers are those squishy things in your nostrils
that appear during interviews and dates. They're not pretty, but as we learned
from this site on kids' health, they
are necessary.

Boogers "happen" when your nasal
mucus combines with dirt and debris you breathe during the day. Mucus (aka
"snot") prevents the dirt from reaching your lungs. Without it, infections would
be far more common.

So, long and disgusting story short, the mucus eventually dries around
the dirt and debris and -- voilà! -- a beautiful new booger is formed. Consider
this the ideal time to bust out the hankie, tissue, or sleeve, then blow.

Yep...lucky me...this was the first thing that I read this morning. Figured I'd share.

HA!
