42 Year Old Paul Ryan

When I was a kid, Vice Presidents such as Spiro Agnew and Nelson Rockefeller and Walter Mondale looked like old dudes to me.  Now, I see that Paul Ryan is 4 years younger than me.  I knew this day would come but I'm wondering what happened?  Where did the time go?   Ryan and Romney both have good hair. There must be some swing voters who are attracted to that?  Are Brad D. and Paul K. at the margin?
