Maybe the Sisterhood's potion did more than just regenerate him~? They did say that Timelord Science was perfected or some-such, suggesting they new more than just what we saw. What if their elixir rejuvenated (i.e. knocking a century or two of the Doctor's age) at the expense of a body that burned out quicker? That would explain why Eccleston was 'younger' than McCoy, and also how Hurt aged so quickly.
