Inside the rocket, your brain has slowed down, and therefore, when you look at your watch, it seems normal, because the watch has slowed down, your brain has slowed down, everything has slowed down, and that's how you resolve all the paradoxes of relativity theory. People forget that. You have to take into account that your brain has also slowed down, so everything you measure is screwed up as a consequence.
