You hug the bolster when you sleep right?
Now think about this. On night 1, you hug the bolster to sleep. You
brought it close to your face, and had your cheeks lean to the side
of the bolster. Somewhere during the night, you start drooling. It
drools on your bolster, dries up partially and you think its ok,
since its your face and your saliva right?
Now in the morning, you put the bolster back to where it was before
you went to bed. On night 2, you hugged the same bolster. There's
now a 50% chance that the position that you had your face on and
drooled on is now IN BETWEEN YOUR LEGS!
On night, the same position may be on your face again.
Now tell me, shouldn't bolsters be banned?
