Your Belly Button Is Filthy  Here's some happy news for
germaphobes: your belly button, or "umbilicus" as scientists
call it, is absolutely filthy, with over 2,000 different types
of bacteria living in it. As ABC News puts it, this "means you
have more kinds of bacteria in your belly button than there are
different kinds of ants or birds in North America."  Even more
exciting is the fact that everyone's gross navel is unique; not
one common type of bacteria was found in the 60 belly buttons
sampled and most strands were "rare and occurred in just one
individual."  For your average person, this might come as a
disgusting surprise, but belly button experts are pretty blasé.
"I don't find it alarming," said Dr. William Schaffner, an
expert in infectious diseases at Vanderbilt University Medical
Center in Nashville, Tenn. "We knew belly buttons weren't
sterile."  At least one scientist, Dr. Gregory Poland of the
Mayo Clinic, is hoping the findings shed light on one of
society's most dangerous and "current" trend
