Listen up – here’s some excellent Monday morning news.

We know that having a stack of fruit and veg every day keeps us healthier, but now it turns out that it can also make us happier. As does having more casual sex.

Two separate studies into happiness have concluded that happiness can be derived from both activities – meaning no more food or sex quandaries.

The first study, published in the American Journal of Public Health, analysed the food diaries of over 12,000 Australians over a six year period to assess their life satisfaction. They were asked to increase their fruit and veg intake from almost nothing, to eight portions a day. And apparently it made them all really bloody happy.

Why?

Apparently, the increase in life satisfaction, happiness and well-being was akin to the psychological improvement felt when you finally land a job after a spell of unemployment.

The study concluded that the ‘well-being improvements from increased consumption of fruit and vegetables are closer to immediate’, compared to the notion of over all well-eating – the benefits of which are experienced much later in life (i.e. when you’re older and haven’t succumbed to diabetes, for example).

Now to the sex part.

The other study followed 371 college students around for 12 weeks to assess their lifestyles, and researchers concluded that casual sex can improve self-confidence. They also found that those who had more casual sex had higher self-esteem.

‘Sociosexually unrestricted students typically reported higher well-being after having casual sex compared to not having casual sex,’ the report stated – and that was for both sexes.

So there we have it – more veg, fruit, sex = happier life.

Do not combine unless absolutely sure about what you’re doing.

And by casual sex, they obviously meant ~safe~ sex. Nobody’s lives are made happier by having crabs or warts. Just a thought.

Study Concludes That Women Who Squirt During Sex Are Actually Peeing

When aroused, some women may experience squirting, or a rather noticeable discharge of fluid. What it is exactly and where it comes from has been hotly debated: female ejaculation or adult bedwetting? Researchers are now saying that squirting is essentially involuntary urination.

Female ejaculate is technically the small amount of milky white fluid that’s expressed when climaxing, New Scientist explains. Squirting, on the other hand, results in a much larger gush of a clear fluid, which comes from the urethra, the duct where urine is conveyed from the bladder. The findings, which combine biochemical analyses with pelvic ultrasounds, were published in the Journal of Sexual Medicine on Christmas Eve.

A French team led by Samuel Salama from Hopital Privé de Parly II recruited seven healthy women—who’ve reported recurrent and massive fluid emission (enough to fill a cup) during sexual stimulation—to undergo “provoked sexual arousal.” The team conducted pelvic ultrasound scans after urination and during sexual excitation just before and after the squirting event.

All of the women had empty bladders before sexual excitation, however, urine collected just before squirting showed that the bladder was filling up. Urine sampled after squirting revealed that the bladder had been emptied again, revealing the origin of the squirted liquid.

The researchers also analyzed chemical concentrations in the urine samples (before arousal and after squirting) as well as the squirting sample itself. These included urea, uric acid, creatinine (a byproduct of muscle metabolism), and prostatic-specific antigen (PSA). The latter is a protein that’s produced in men’s prostate glands and in the “female prostate” called the Skene glands; PSA is found in “true” female ejaculate. Urea, uric acid, and creatinine concentrations were comparable in all of the urine and squirt samples. However, PSA, which was not detected before sexual simulation in six of the women’s urine samples, were present in urine collected after squirting and in the squirt sample in five of the women.

Squirting, they found, is essentially the involuntary emission of urine during sexual activity—though there’s also a small contribution of prostatic secretions as well. Salama’s team is now working on a protocol to test whether the kidneys work faster to produce urine during sexual stimulation than at other times, New Scientist explains. And if so, why.
