Okay, not to suddenly become the Fan Theorist type of Doctor Who fan, but I have a legitimate question:

Seeing the various doctors next to each other gives you a far better idea of their unique heights and builds than just a list of their heights.  According to the Law of Conservation of Mass, matter cannot be created or destroyed, just changed. Considering there’s an explanation for everything in the Doctor Who universe, I would just like to know:

Does the Doctor always have the same amount of matter? Is it simply converted into different aspects? (Denser bones? More/less hair?) Or is extra matter expelled post-regeneration?  (I mean, look at Tom Baker vs. Sylvester McCoy. I know they weren’t back-to-back, but comparatively speaking, Sylvester is like a little shih tzu I could carry in my purse forever and ever.)

And if that was the case, how would larger doctors suddenly gain more matter for additional height/mass/etc.?

Am I overthinking things, or has this been previously discussed?
