A good habit of exercise and diet is self-reinforcing. What is the difference between self-reinforcing and habit-forming? I see three differences. 1. Who is in control? A runner is in relatively more control, because the act of running does not require a gamified online experience. 2. What are the ethical ramifications? These are subjective. To be clear, subjective certainly does not mean unimportant. It means people may disagree. In my view, people largely disagree on the "margins" of ethics -- meaning there is a wide swath of common ground. 3. There are some physiological differences; I'm not an expert. It seems that both the runner's high [1] and social media involve dopamine, but they appear to use different mechanisms. ("Runner's high" seems to involve endorphins as a precursor.)
