Adrenaline May Damage DNA

Yeah, but it's gotta be stress-inducing when he gets conflicting directives from different banks.
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 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.
Yeah it sounds really obvious, until you realize they're figuring out the actual biochemical mechanism behind it. Stress also increases the chance of heart disease and cancer. P53 (or specifically its failure) is also involved in many cancers.
It looks like useless research on the surface, for the lay person. But when you dig into it you realize that if you can map out the biochemical pathway, you can think about designing drugs to block certain parts of it - resulting in prolonged life or decreases tumor incidence, for example. Stuff like this actually is important.
