Now, that's great, but it sort of points to a pathway whereby, okay, you know that you should exercise, you tell yourself that you should exercise, you're emotional about it, and your adrenals release adrenaline, and you exercise. Now, that's interesting. But what is perhaps far more interesting, is that the data from Strick Lab, and other labs as well, shows that when we move the large muscles of our body, the adrenals release adrenaline, epinephrine.
