250 ms before you remember it occurring to you. From what I understand, your body makes you think you arrived at a decision later. This way, you're not constantly aware of how long your thoughts take to process.

Good point. When I heard this fact, I thought to myself, '250 ms before you are aware you are aware of it.' When someone makes a decision -- in the fact I read, it appeared that the brain selecting something to buy a moment before a person thought they chose. But it stands to reason that a process of choosing would have several steps, at least one making the choice and another step 'submitting' the choice to conscious awareness a moment later. But perhaps this was addressed in the original articles.
