This is also my theory. For children, lots of stuff in their lives is new and noteworthy, so they're making new memories all the time. Therefore, time seems slower because they have so many data points to refer back to. I'm nearly 50 and so much of my daily life is routine and definitely _not _ noteworthy. The memories I form are much more sparse. Therefore, time seems to fly by, because there are much fewer data points to reference.
