We are very, very sloppy with language.
Consider the word “can’t”. People use it often, casually, and, mostly, inaccurately.
As in: I just can’t seem to lose weight. Actually, barring a genuine medical disorder, the odds against somewhere in the 25,000 to 1 range, anybody can, in fact, lose weight. There’s no mystery to it whatsoever. Reduce calorie, fat, and empty carb intake, add exercise. The accurate word replacing can’t here would be choose. I just seem to choose not to lose weight. I choose to remain fat, ugly, unhealthy.
