56 Up was the first one I had seen. And it really does give you a sense of mortality and how quick life's years can go by, in a blur of routine.
There are 29.453.760 minutes in 56 years. There were 14 people, for a total of 412.352.640 minutes of lifetime.
That a speed up factor of 536.219. It seems like any biological system sped up 500k times it's normal rate is going to give a sense of mortality.
Reminds me of a guy who shot 1 second every day for a year to make a video. He ended up on Ted's main stage and ended up making an app.
