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

Philippe
