If Rule #1 is "The Doctor always lies", Rule #1A is "The Doctor is always running". Since Doctor Who began back in 1963, the Doctor has been running from something. For a long time, it was his fellow Time Lords, as he actually stole the TARDIS from Gallifrey to escape the planet to begin with. A In NuWho, the Doctor has taken to running to keep himself alive. He has ran from legends, prophecies and even attempted to run from the universe itself (after he faked his death, he attempted to disappear from the universe to keep a low profile). All this running has done one thing for this Time Lord, as he has surpassed 2,000 years old with no signs of slowing down any time soon, especially now with a brand new regeneration cycle bequeathed to him by those very same Time Lords he's spent most of his life running away from. Lesson Learned: Sometimes it's OK to run away to fight another day. Don't think it makes you any less of a person.
