This post is extremely speculative and the author stretches the CS analogies way, way too far, but the gist is reasonably accurate. Time does pass faster on average as you get older because our brain doesn't bother to record repeated experiences.

But guess what? That means that all you have to do to make time pass more slowly is bring more novelty into your life. I can say from personal experience that the year I spent living abroad seemed to go on forever. Every single day was filled with new experiences. There was a huge amount of continuous novelty and learning and growth. It was really nice. I need to move to a new country again.
