I’ve seen these sorts of videos before, but this one is especially good. The parents of “Natalie” took her photo almost every day for ten years to create this video. She ages a year every 9 seconds, a bit less than on month per second.

I’m fascinated by the many hostile comments under this video at YouTube. Why is this video so disturbing to so many people? The great dedication of Natalie’s parents to this video has enabled us to see something that can’t otherwise see day-to-day. Are so many people hostile because that watching this photo montage reminds them that they are mortal, that we are human animals? Or is it the result of decades of put-down humor pumped into Americans by sitcoms? Or something else?
