    If this were true in all cases, people like me would be in trouble. I run 50+ miles per week and the runner's adrenaline high is a part of my daily life. However, it has to be balanced with the benefit of aerobic exercise: http://www.natap.org/2011/HIV/081911_03.htm [natap.org] That said, I'd imagine most heads of states don't put in those kind of miles, and the CNN article (mostly about Obama) is far from scientific. "Looking older" has shit to do with overall health in many cases. However, the study seems to imply chronically elevated adrenaline levels--and athletes have anything but. Catch us before or after a workout, and many of us* are some of the most mellow people you could meet (because the stress relief offered by heavy exercise is a hell of a boon). Personally, I think that's the key that many people who "read" this article will miss: stress keeps adrenaline *chronically* elevated.
