Ok then go put your friend between you and the mirror such that he or she<br>
faces the mirror,<br>

Hi,<br>
seems to me that it is a matter of definition. You say that your<br>
right/left hand are exchange because when you look at the image in th<br>
mirror the left hand is situated on the left of your virtual body. This<br>
hand being on the your right hand side in the real you...<br>
Now , for your head: if you define your head as the thing on the left<br>
hand side of your heart (when you look at your heart sitting on the<br>
middle of your chest). Then, in the mirror, your head is at your feet.<br>
Thank God for that...<br>
<br>
