How do we reconcile this abstract notion of chronological time? Perhaps through our own experience and the stories we hear and tell.
Why 15 minutes of fame and not 10, 12 or 16 minutes? Laurie Andersen told the audience in one of her performances that 15 minutes was the time that it took for an intercontinental ballistic missile to fly from the former Soviet Union to the United States.
Why do men and women in Japan choose different times to kill themselves? Men often commit suicides in the early hours of the morning, when the family is asleep. The women, on the other hand, after the children have gone to school.
A fascinating observation by one of the Pro-Democracy protestors from Hong Kong as described by the South China Morning Post.
"It's an enjoyment to be here. Here in Admiralty, you can find a more humane Hong Kong where people are helping each other out every minute," says Cheung. "There is no noise from traffic, but birds singing. You see trees, you live a way slower pace of life ... it's beautiful," he says. "It gives people an opportunity to experience the preciousness of public space."

"I lived and studied under the path (where the banking occurs) of the Rwy 13 Approach back then, it was noisy enough to interrupt our teacher every 3 minutes for say 20 seconds. And there was "always" a plane departing in between the 3 minutes interval, although not as noisy as it flew over towards the sea. I also noticed that, the local players, namely Cathay Pacific, usually made the approach path a bit wider and a bit more towards the hill so they can have a longer final and a shallower angle of turn, then the published procedure. Also rememered I can occasionally feel and hear the wake turbulance even from a meduim weight aircraft, from my school playing ground in the good old days...Long live Kai Tak."
