The Passage of Time

Today is my 58th birthday. It would appear that I have existed for nearly six decades. Put another way, I am over half a century old. All of which has given me pause for thought with regard to the passage of time. A phrase that is often bandied about, but what exactly does it mean? As I understand it, the “passage of time” refers to our perception of the flow of time and how we experience its movement. This is something distinct and different from objective time as measured by clocks. Our subjective experience of time can vary due to multiple factors. Two common examples are how time can feel like it's flying by when we're having fun and enjoying something or dragging its feet when you’re enduring something dull. Other factors are whether we are applying ourselves to a task, concentrating and general activity. Such focus can make time pass quickly.
