My theory is it's just about boundary pushing. When you're younger, the boundaries are closer and easier to find because you have limited experience with the world. As you get older, The boundaries appear to extend farther and farther away, and you get more comfortable staying away from them. I say this because anecdotally, I have a few years in my twenties that seem like they flew by, because I was living a pretty boring life working in an office. But then later in my thirties I have some 3-month periods that stretch wider and longer in my memory then those entire years in my twenties, because I was out and exploring.
