This YouTube video is amazing in that it takes the viewer from age zero to 100 in 150 seconds.
A camera stays fixed to a close-up of 100 people starting from an infant to a centenarian who state their ages for the camera. Of course, the baby that stands in for zero gurgles at the camera, and the one-year-old’s age is proclaimed by a woman off camera. But, by watching the progression of images, you get the sense of the wonder of the aging process and of the utter humanity of it all.
It’s in Dutch, so the bonus is if you don’t already know Dutch, you can also learn to count to 100 in that language.
