Over The Counter Culture

Mice and rats infected with toxoplasmosis are less scared of cats and can even start ‘deliberately’ hanging around areas where they can smell cats. Inevitably, that means they’ll get eaten, the cat will get the disease, and will help spread it around.

In humans, there is some evidence that toxoplasmosis is linked to schizophrenia.

Most amazingly, in women who get toxoplasmosis, the likelihood of a boy being born goes from slightly over 50% potentially all the way up to 72% – so for every 10 girls, 26 boys would be born.

If you have a specific blood type (Rh-), you’re 2.5 times more likely to have a car accident than uninfected people.

There’s controversial evidence that men become more anti-social, grumpy, risky/rebellious, but less curious – and that women become friendlier, keener to have sex, more outgoing, and might be considered more attractive by men.

In most healthy human beings, toxoplasmosis merely presents with flu-like symptoms, then sits dormant.

Snippets from some astounding happiness, obesity and widowhood research. via Chris Dillow on Stumbling & Mumbling (with more findings, details on what was controlled for, and his thoughts as to whether this is true, and what it shows)

Marina-Selini Katsaiti finds that “obesity has a negative and statistically significant effect on individual well being”. She estimates that, in Germany, a three-point rise in BMI (from, say 24 to 27 – equivalent to gaining around 20 pounds for someone who’s 5’8”) reduces happiness on average by so much that it would require a 67% pay rise to compensate. In Australia it would require a doubling of income to offset the adverse effect of such a weight gain.
Now, contrast this to a new paper (pdf) by Andrew Clark and Yannis Georgellis. They show that, in the UK, men and women who have been widowed are happier in the 3-4 years after their loss than they were the year before it. Yes, their well-being slumps in the 12 months after bereavement, but it recovers thereafter.

Now, remember of course that winning the lottery will statistically do very little, if anything, to make you a happier person in the long run

How very peculiar!

The mere presence of salads on a McDonalds menu makes people more likely to consume the unhealthier food, according to a new paper published last month. Here’s the abstract:

This research examines how consumers’ food choices differ when healthy items are included in a choice set compared with when they are not available. Results demonstrate that individuals are, ironically, more likely to make indulgent food choices when a healthy item is available compared to when it is not available. The influence of the healthy item on indulgent choice is stronger for those with higher levels of self?control. Support is found for a goal?activation?based explanation for these findings, whereby the mere presence of the healthy food option vicariously fulfills nutrition?related goals and provides consumers with a license to indulge

One thing to consider, though – true or not, there’s a rumour floating around that the salads are unhealthier due to the oily dressing. Shouldn’t this have been controlled for in the study?

How I wish that instead of dull sermons from the chaplain or stern slobbers from the headmaster, assembly at school had been a TED video (or better yet, a live speaker of that caliber).

What a way to start the day.

Here’s a particularly interesting one I just watched, prompting further reading and me seeking to reconnect with an entrepreneur in the electric car industry:

Shai Agassi discusses the economics of mass electric car adoption in a scheme involving removable electric batteries and universal charge points that completely rethinks the economics of running a car. You get paid if you have to change your battery more than x times a year.
