Your coworker sounds like a dingleberry honestly. Generally speaking in the psychological world, before an addiction can even be identified as one, there has to be a pronounced and usually detrimental change in the way you live your life or treat those around you, either directly or indirectly as a result of the thing you are addicted.
What you do might be described as whats called a "soft addiction." These are basically compulsions that either have begnin (like you) or relatively harmless side effects and do not present an immediate and/or grave danger to one's health. Some soft addictions include overeating(although that's starting to become more debated among the psychological community), using the internet too much, shopping, or reading excessively. Usually these are things that most people have to do daily to live or make their lives simpler, with the exception they are taken to the next level and done excessively.
