Have you watched the «Face Off» movie? I hope, you have. And I hope, that you like it, as I am fond of it. I like the idea of this movie - to cut off the faces of two different people with the laser, to exchange them, to exchange their voice, or to change their lives in general.
And would you like to change physically your appearance, for example to live a life of the best friend. I think, it would be very interesting experiment.
