2015 Ig Nobel award for Politics, right there.<p>I love this kind of 'research'. It's frivolous, but there is an underlying point about the stressfulness of presidency.
I was under the impression that presidents dye their hair regularly.<p>If a politician is too old - dye out some (or all) of the gray. Reagan being an extreme example - not a single gray hair.<p>If a politician is young - Clinton, Bush, Obama - add some gray, until nature catches up.<p>Gray hair conveys "gravitas" - age, and experience - exploits a natural human bias. I'm sure this is focus-grouped to death. This all being in the age of Color TV and HDTV of course - I doubt Kennedy stooped to this level. Pretty punishing, and just imagine a 4K picture or better down the road.

I think this line sums up the study best for me.
It's not the stress of his job that is graying his hair it is the fact that BO continues to smoke cigarettes. shameful (particulry since his major accomplishment is ACA.)
