*** REPLACE THIS LINE WITH YOUR MESSAGE ***

I always believed that the umbilical cord was tied giving the shape.
In fact this is not true. As any parent knows, after cutting the cord, a
stump is left. Modern medicine uses a plastic clamp to seal the end (no
knots). In fact, the clamp is applied before the cutting of the cord.
In any case, the stump falls off by itself in a few weeks 
leaving a navel.
    Maybe a medical person can explain why some are in-y and others are
out-y.
