Sorry if this has been asked/answered before, but I have a question regarding how Time Lords age in their first regeneration. When we meet the First Doctor in An Unearthly Child, he's |~236 hundreds of years old and looks like an old man, but not that old by human standards. Susan, on the other hand, looks like a teenager, and I don't thiiink we're ever told how old she specifically is (though I could be wrong about that). The Doctor says in one episode that he visited the Medusa Cascade when he was 90-years-old and said that he was just a child then.
Do we have any idea (from any sources, be they TV canon or the looser expanded canon) what the aging rate is compared to human aging? Is it similar up until they hit the earlier stages of old age, then it just STOPS, and from then on, the next regenerations pick a look that never ages no matter how long it lasts? Or is it really slowed down so that he would have literally been a child/teen visually at 90? Then I saw that he apparently spent centuries at the Academy, but I'm veeeery unknowledgable about the expanded canon and generally less knowledgeable about Classic Who (though I'm doing my best to remedy that asap). Also, when I was poking at Susan's information, it sounded like she never actually got physically old, despite it being presumably her first regeneration (though that isn't TV canon and thus may be flexible, I dunno).
I was just curious about people's knowledge/thoughts on the matter so I can try to wrap my mind around it, as we don't see much of that "first regeneration" stage in canon.
