Caerphilly is a small commuter town in South Wales, notable mainly for Caerphilly cheese and a castle.

Well, you can add one more thing to that list; its inhabitants also provided some key data in a major health study, from which emerged one great finding — it turns out that if you’re male, sex twice a week reduces the risk of death from heart disease by about half:

Men who said they had sex twice a week had a risk of dying half that of the less passionate participants who said they had sex once a month, Dr. Davey-Smith’s team said.

No other risk factor showed a statistically significant link to the frequency of orgasm.

The authors said that they had tried to adjust the study’s design to account for a factor that might explain the findings — that healthier, fitter men with more healthy life styles engaged in more sex. Even so, they could not explain the differences in risk. Hormonal effects on the body resulting from frequent sex could be among other possible explanations for the findings, Dr. Davey-Smith said.

Here’s the science bit, via the BMJ — a paper entitled ‘Sex and death: are they related? Findings from the Caerphilly cohort study’:

Result: Mortality risk was 50% lower in the group with high orgasmic frequency than in the group with low orgasmic frequency, with evidence of a dose-response relation across the groups. Age adjusted odds ratio for all cause mortality was 2.0 for the group with low frequency of orgasm (95% confidence interval 1.1 to 3.5, test for trend P=0.02). With adjustment for risk factors this became 1.9 (1.0 to 3.4, test for trend P=0.04). Death from coronary heart disease and from other causes showed similar associations with frequency of orgasm, although the gradient was most marked for deaths from coronary heart disease. Analysed in terms of actual frequency of orgasm, the odds ratio for total mortality associated with an increase in 100 orgasms per year was 0.64 (0.44 to 0.95).

Conclusion: Sexual activity seems to have a protective effect on men’s health.

The perfect excuse ;) Thanks, Caerphilly!

Funny: According to a ‘top Austrian doctor’, picking your nose and eating it is good for you:

‘Medically it makes great sense and is a perfectly natural thing to do. In terms of the immune system the nose is a filter in which a great deal of bacteria are collected, and when this mixture arrives in the intestines it works just like a medicine.

‘Modern medicine is constantly trying to do the same thing through far more complicated methods, people who pick their nose and eat it get a natural boost to their immune system for free.’

That’s the message from Robert Sapolsky, professor of biological sciences at Stanford and neurology at Stanford’s School of Medicine, from his studies of baboon behaviour in the Serengeti:

For the humans who would like to know what it takes to be an alpha man–if I were 25 and asked that question I would certainly say competitive prowess is important–balls, translated into the more abstractly demanding social realm of humans. What’s clear to me now at 45 is, screw the alpha male stuff. Go for an alternative strategy. Go for the social affiliation, build relationships with females, don’t waste your time trying to figure out how to be the most adept socially cagy male-male competitor. Amazingly enough that’s not what pays off in that system. Go for the affiliative stuff and bypass the male crap. I could not have said that when I was 25.

A handful of (the baboons) simply walked away from it over the years. Nathaniel was one, and Joshua was another. They had the lowest stress hormone levels you’ve ever seen in male baboons, and outlived their cohorts. The fact that this alternative strategy is actually the more adaptive one is one of the good bits of news to come out of primatology in quite some time. If that’s the future of primates, this planet is going to be in great shape in a couple of million years.

A great article, and pretty funny in places — especially where he discusses the results of baboons’ lack of a developed frontal cortex:

Even though there are tremendous individual differences among the baboons, they’re still at this neurological disadvantage, compared to the apes, and thus they typically blow it at just the right time. They could be scheming these incredible coalitions, but at the last moment, one decides to slash his partner in the ass instead of the guy they’re going after, just because he can get away with it for three seconds. The whole world is three seconds long–they’re very pointillist in their emotions.
