I don't know why . . . but I cry every time I watch one of these.  And, since 2013 is drawing to its close, Google has made me cry again with its year-end review.  Here's the video compilation of what people searched for on Google in the past year.  And, as always, it's a testament to the triumph of the human spirit, the beauty of the Earth, social progression, great moments in sports, music, history and more.  Wanna see?
