My anecdotal personal experience aligns well with this! I am not an adrenaline junky, but I have noticed that one of the reasons I enjoy mountain biking so much is the effect the perceived danger has on my brain. A challenging down-hill run will zero-in my focus to just what is necessary to avoid disaster (I am not great at mtn biking...). My mind is emptied of all else! Very similar feeling to what I experience when meditating!
