I'm sorry, but most of the posts in this thread are making me mentally shoot the middle finger. I think my anger is just a primal response that I have when I feel threatened or stressed. When I'm jogging, my heart is racing and my adrenaline level is high, so I become very defensive, like a caveperson being chased by a dinosaur or cannibal. When reading this thread, I'm absorbing a lot of criticism and chastising, which also trigger defensiveness.

If my state (Texas) or the federal government eventually legalizes marijuana, I may finally be cured. Until then, I suppose I'll continue to release my anger in the relatively harmless ways that I do (I promise that I will never allow myself to carry a gun or knife on my jogs and hikes). Few, if any, drivers seem to notice my flipping, since I just release the middle finger from one or both of my closed fists as I continue to move my arms back and forth (also, I usually start right after they pass, so it's not coming up in their face).
