I have a forensic facial reconstruction from skeletal remains questions/comment

First off I would like to say I love your videos/show, Good Mythical Morning!

I have a few questions or more of a comment really based on one of your videos:

Why Couples Look Alike

FFRFSR is a neat process which is pretty accurate. But I wonder how this is achieved based on the above mentioned show, and it also posed the question of bone structure changing over time due to the scientist theory. It made me think if I had the money to do it, I would love to get a 3D model of  my wife's and my skulls, possibly at different intervals of our life/relationship and see how accurate it would be based on the theory. Can muscle structure effect bone over time? What is the correlation here to the above mentioned show? There is a lot of conflicting information on the net. What's your take on this?

Thank you very much!
