Sept 11 Anniversary

Hillary Clinton's stumbles as she left Sunday's 9/11 memorial ceremony put her health at the forefront of a presidential campaign in which the two major party nominees are among the oldest ever and have disclosed a limited amount of information about their medical history.

Americans commemorated the 15th anniversary of the Sept. 11, 2001 attacks on Sunday with the recital of the names of the dead, tolling church bells and a tribute in lights at the site where New York City's massive twin towers collapsed.

After the roar, after the first ground-trembling collapse sent clouds of pulverized matter billowing through Lower Manhattan, a man paused from his hurried retreat to take in a world now coated with the dust of uncertain gray. For reasons he still cannot explain, he bent down, scooped some of this grayness into an envelope - and kept on moving.
