40 Facts About Sleep….

Interesting.

*Anything less than five minutes to fall asleep at night means you’re sleep deprived. The ideal is between 10 and 15 minutes, meaning you’re still tired enough to sleep deeply, but not so exhausted you feel sleepy by day.

Scientists have not been able to explain a 1998 study showing a bright light shone on the backs of human knees can reset the brain’s sleep-wake clock.

The “natural alarm clock” which enables some people to wake up more or less when they want to is caused by a burst of the stress hormone adrenocorticotropin. Researchers say this reflects an unconscious anticipation of the stress of waking up.

Transcript of “The Diamond Empire”

A Frontline show from ten years ago about one of the biggest scams of all time.

EDWARD EPSTEIN, Author, “The Rise and Fall of Diamonds”: Well, what I learned was that the diamond business wasn’t a business of extracting, as I originally expected, something of enormous value and then simply seeing how much of this object you could get out of the ground and selling it. That was what the business appeared to be when I started my venture. But their real business was restricting what came out of the ground, restricting what was discovered, restricting what got cut, restricting what actually found its way into the retail market and, at the same time, through movies, through advertising, through Hollywood, through the manipulation of perceptions, creating the idea that there was this enormous demand for these shiny little objects that they seemed to have in abundant supply. So I wound up on this voyage of discovery starting off with the idea that there was this object of great value, and it was just a question of how many could you get out, and I wound up discovering it was just the opposite.

NARRATOR: This is the story of how that grand illusion was created, and the story of how one family gained control of the world’s diamond trade and for nearly a century has maintained its hold on an empire that defines the very idea of what diamonds really are.

Taking Passwords to the Grave

From Wired:

William Talcott, a prominent San Francisco poet with dual Irish citizenship, had fans all over the world. But when he died in June of bone marrow cancer, his daughter couldn’t notify most of his contacts because his e-mail account–and the online address book he used–was locked up.

Talcott, 69, a friend of beatnik Neal Cassady, apparently took his password to the grave.

It’s a vexing, and increasingly common problem for families mourning the loss of loved ones. As more and more people move their lives, address books, calendars, financial information, online, they are taking a risk that some information formerly filed away in folders and desks might never be recovered. That is, unless they share their passwords, which poses security threats.

“He did not keep a hard copy address book. I think everything was online,” said Talcott’s daughter, Julie Talcott-Fuller. “There were people he knew that I haven’t been able to contact. It’s been very hard.”
