French diet guru Pierre Dukan is urging his government to give extra marks in school for a healthy BMI. The Telegraphreports:
"Obesity is a real public health problem that is rarely – if at all – taken into account by politicians," Mr Dukan told newspaper Le Parisien ahead of the book's launch.
Mr Dukan said his education plan would be "a good way to sensitise teenagers to the need for a balanced diet."
He denied it would punish overweight children, saying: "There is nothing wrong with educating children about nutrition. This will not change anything for those who do not need to lose weight. For the others, it will motivate them."
A while back, a reader sent us this photo, with a warning you rarely see in the U.S.
In light of our recent podcast "The Perils of Drunk Walking," we got in touch with Kon Scholtz, head of marketing and sales at United National Breweries, the South African company that makes the beer in question, Chibuku Shake Shake. Scholtz told us that Shake Shake is a nickname for traditional African beer made from maize and malt; it has a short shelf life (about five days), a relatively low alcohol content (3.5%) and, is meant to be shaken before consumption. It is also, according to Scholtz, very nutritional.
As for the warning on the carton, Scholtz explained.
I happen to have one, and it's been working without a hitch since 2006. I've never had an incentive to replace it for a few key reasons: I think it's aesthetically pleasing, storage space isn't a problem for me, and battery life isn't a problem either -- I use it on my daily commute. I also prefer buttons to touch screens.
But after seeing photos of a melting iPod due to the battery problem, I'm inclined to take part. Especially after I learned I'd be getting the same product, just new and without the fear of fire.
Here's the hidden cost of a recall, though: Apple will send the new product to me 6 to 8 weeks after they've received my old one.
In our latest Freakonomics Radio podcast, “Misadventures in Baby-Making,” we describe an academic paper by a Dutch mathematics professor that might have been one of the inspirations of the controversial One Child Policy in China.
“Given a certain initial age profile the population must be "steered" as quickly as possible to another, prescribed, final age profile by means of a suitable chosen birth rate.”
The model considered the natural birth rate and mortality rate, an economic constraint, and time. And like any good empirical scientist, Olsder makes this warning in his paper:
“This paper is not concerned with the social and political problems involved in establishing the best mechanism for a program of population management....The optimal birth rate may unbalance the age distribution during the time interval concerned, which could give rise to economic and social problems.”
Last weekend, I was walking around New York's Lower East Side when I stumbled upon an interesting restaurant. The counter was serving Thai food, but they didn't take cash - they only took time.
For a home-cooked lunch (with table service), I was told I'd have to pay with a half-hour of my time. This was an alternative economy staged by artists Julieta Aranda and Anton Vidokle as part of Creative Time's Living as Form exhibition, part of a larger community movement of time banks going on nationally.
A time bank is not a barter system. Your good (or service) is not directly exchanged for another good or service. There's a medium of exchange: it's time, not money.
Radiohead is famous for doing price experiments with fans. At the height of illegal downloads, the band asked fans to pay-what-you-want for their album. They picked a small venue in New York -- the Roseland Ballroom which accommodates 3,000 instead of Madison Square Garden which seats about 20,000 -- and limiting ticket sales to 2 per customer. But can limiting supply like this really stop a black market from emerging?
Tetlock is a psychologist at the University of Pennsylvania, well-known for his book Expert Political Judgment, in which he tracked 80,000 predictions over the course of 20 years. Turns out that humans are not great at predicting the future, and experts do just a bit better than a random guessing strategy.
In the last Freakonomics Radio episode “The Suicide Paradox,” (You can download/subscribe at iTunes, get the RSS feed, listen live via the media player above, or read the transcript here) we talked to a San Francisco cabbie with a long name who said something that caught our attention:
One night I picked up a guy, I think down nearby Tenderloin and he want to go Golden Gate Bridge. Must be 11 o’clock at night. And I said “okay,” so I drove on Franklin Street. He said, “You want to ask me why I go to Golden Gate Bridge this late?” I said, “No, but if you want to tell me I guess I will listen to it.”
And he said “I’m going to go and jump off the Golden Gate Bridge” and I said, “Okay.” He said, “You’re not going to stop me?” I said, “No, why should I?”
The cabbie doesn't know what happened to his passenger, but he did call the coast guard immediately afterwards. Suicide isn't illegal in the U.S., and as a citizen of a country that prides itself on individual rights - what would you do?
Our Virgil in the journey was David Lester, a professor at Richard Stockton College of New Jersey and the dean of suicide studies. Lester is prolific: he has over 1000 citations regarding suicide on a wide range of topics, from quirky informal studies to serious stats. He's written about which day of the week suicide occurs the most, what blood type suicide rates are associated with, and whether suicide rates are higher in nations with greater rainfall.
In the latest Freakonomics Radio podcast,'The Suicide Paradox," we explore, among other things, why suicide is twice as prevalent in the U.S. as murder. From the CDC, here's a breakdown of state-by-state suicide and homicide rates.
