A few months ago I went on a holiday trip to the mountains. After traveling I turned my phone off. My days were filled with walking, eating or reading books on an e-reader. I was surprised by how much this slowed time! It was a happy time, yet I did not feel bored or like having fun.

Time seems fast when I'm distracted, hurried, pressured. It seems slow when I have few obligations, think deeply, enjoy nature. The speed of time may be a property of the state of the mind.
