Ways to use Intervals:
Why have multiple running timers if I can't physically do more than one thing at a time?

   That's a good question. It makes sense that if a person can only do one thing at a time, then there should only be one timer running at any given moment. The reason for having simultaneous timers is that we are often tracking more than just people. We use timers to track parallel processes. In other words, multiple timers let us track our time spent multi-tasking.
   
   For example, I might start a sync script running and want to know how long it ran. While it's running, i'll knock out a few other tasks. I need to run a timer for each of those tasks, in addition to the timer already tracking the sync script.
   
   In our digital age, we are accustomed to automated tasks that do parts of our job for us. Allowing multiple simultaneous timers enables us to track each of these side tasks.
