There's a lot of research about how exercise is allegedly good for non-physical things, like mood or cognition.
Articles about this research often state as a given that exercise makes you feel good emotionally and boosts your mood.
However, for me, exercise makes me angry with no positive mental or emotional effects. I've blogged about this before, and over the years it has attracted the attention of others who are angered by exercise.
Someone should study whether exercise has the same alleged non-physical benefits for people whom it angers as it does for the general population. What if being made angry by exercise is a sign that it doesn't have those benefits for you?
