Yes, all of these things involve adreneline, and filling up with it and burning it off. That is not "trauma" at all. Trauma stops a person in their tracks and shocks their system and challenges the emotions and makes the person feel powerless. Adreneline energizes, cortizol stresses the system. Adreneline can also produce dopamine, cortizol doesn't.

Maybe you could try running? Something that requires adreneline? Or rock wall climbing?
