It’s very odd when you begin to see your peers die from their habits. A whole new terrain. I knew a bright, charismatic, albeit troubled man, who drank and smoked, heavily. I remember thinking (privately) that it was a race to see which would kill him first. One tried and the other finished the job. I miss him. I can’t abide waste and I really hate it in people.
One of the better definitions I’ve heard of addiction is: any behavior done to excess that a person wants to stop or should stop, but can’t on their own.
This seems like a good measuring stick, whether the subject of excess is food or smoking or caffeine or alcohol or drugs or work or hoarding or spending or relationships or cat-owning or the internet or exercise or gambling or… anything.
