[Wien] Very elemental questions...

[Gerhard Fecher]

Seems I have to make the question more complicated.

Do you have a mirror and a friend at hand ?
Ok then go put your friend between you and the mirror such that he or she faces the mirror,
try to answer my question again.

You've got it ?


have fun
Gerhard

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
