You could have someone write "listerine"marker with a thick black on
your foreheard to be sure that your body produces the same results as
the bottle.

Ok so a person turning around changes the image axis as your right
and left reverse. When I first read the OB comment I went to a mirror
then I raised my right hand to my right ear and it was still on the
right side in the mirror image but holding a bottle of Listerine up
produced the words backward. I'm looking straight into the mirror so
my axis of perception has not changed. Why do the word on the
Listerine show up backwards?

Mirror image
If one looks in a mirror, one's image reverses (e.g., if one
raises one's right hand, his left hand will appear to go up in the
mirror). However, a mirror does not "swap" left and right, any
more than it swaps top and bottom. A mirror reverses the
forward/backward axis, and we define left and right relative to
front and back. Flipping front/back and left/right is equivalent
to a rotation of 180 degrees about the vertical axis (in the same
way that text which is back-to-front /and/upside-down simply looks
like it has been rotated 180 degrees on the page). Therefore,
looking at an image of oneself with the front/back axis flipped is
the same as looking at an image with the left/right axis flipped
and the whole figure rotated 180 degrees about the vertical axis,
which is exactly what one sees when standing in front of a mirror.
