For me, a variety of things has a journey that consists a start and an endpoint; humans have a beginning when they are born and a finish when they die, and many nonliving objects have the same path. Their functional cycle commences when they are manufactured and stops when they are broken. Some of the defective stuff can be repaired so it can be used for a long time, but it would not be as good as if they were new.
Running also follows almost a similar path with a slight difference, which is the concept of a restart. When I started running a few years ago, my running was neither fun nor pleasant, so I had to take a break shortly after I start, then Restart the same run. Gradually, I noticed that my break time got shorter and my running distance became longer, and that was a progress. Although there is a restart “button” in running, I do not get the same experience each time.
