Yeah, but an unforgivable number of people simply don’t understand calories, or nutrition, or the benefits of excersise. Like, I know several overweight people, who are profoundly upset at being overweight, but refute the idea that managing calorie intake would help, _genuinely _ believe that all food is equal, and don’t believe excersise would help improve their health.
An operating system isn’t a car or a machine that needs to maintain running hours for optimal performance. If I have an operating system that I only need for one specific function, and only use it for that function, once or twice a month, there is no reason that that operating system should fail to do the one thing I need it to do every time I turn it on.
