Lately, I've been very alert to people who are checked out while doing their job. It's fairly obvious with people who have service jobs, or office workers. It's not always so apparent when I'm observing professionals with high requirements for safety: doctors, first responders, truck drivers, etc. But if at least some percentage of these folks are checked out (or distracted by their phones, their own thoughts or otherwise not fully present), this has incredible ramifications for the people they serve, i.e. all of us.
There is so much competing for our attention all the time. I'm certainly not immune. I'm one inch of finger movement away from checking Facebook RIGHT NOW. What if I'm driving a car at the same time? What if I should be making an important decision at work?
