Clinton weathers job’s long flights

Flying more than 22,000 miles in a week filled with dozens of official meetings, public events and media interviews didn’t seem to have taken a toll on Secretary of State Hillary Rodham Clinton during her much-publicized trip to Asia. How does she do it?

I’ve been asked the same question about three of Mrs. Clinton’s predecessors I’ve traveled with — Condoleezza Rice, Colin L. Powell and Madeleine K. Albright. My answer is always the same, but it’s not the queen-size pullout sofa in their plane’s private cabin, though having a real bed in the air certainly helps.
