A couple of interesting items popped on the scope today. First, is it possible to predict longevity? Well apparently you can when you correlate longevity, wealth, and health. According to one recent study,
[S]cientists have gone a step further, finding a specific hormone that links wealth with a longer life. The hormone is called DHEAS–or dehydroepiandrosterone sulfate–a natural steroid produced by the brain, adrenal glands and sexual organs.
Those with higher levels of DHEAS tend to exercise more, have more hobbies and have closer relationships with friends and family. They also tend to live longer.
I think this is one of those chicken before the egg scenarios. Did the wealth, and time to take care of oneself, cause the hormone or did the hormone cause the good health which caused the wealth? Or something like that.
And speaking of predictive models, did you know that Twitter has a “mood” and that it may be able to predict stock market swings?
Researchers are busy mashing together algorithms to take advantage of the Twitterverse’s stock market predictability.
One algorithm, called the Google-Profile of Mood States (GPOMS), records the level of six states: happiness, kindness, alertness, sureness, vitality and calmness.
So these guys [smart, nerdy guys wearing glasses] took 9.7 million tweets posted by 2.7 million tweeters between March and December 2008 and looked for correlations between the GPOMS indices and whether Dow Jones Industrial Average rose of fell each day.
Their extraordinary conclusion is that there really is a correlation between the Dow Jones Industrial Average and one of the GPOMS indices–calmness.
Unfortunately, there’s no definition of calmness though, apparently, there are degrees of calmness.
