Why would someone bone up on those seemingly uninteresting and inappropriate acts? I would put about the answer lies in the questions this neuroscientist has asked himself: What is a cough? What has unquestionably gone with the wind? Over the years, Provine has investigated these and other behaviors in the lab and on the avenue, and the crop is beautifully written and constantly surprising.

And that is exactly how [ Provine ] thinks science should be pursued. For each of these quaint functions, Provine dexterously combines wit, a fine way with words, and inflexible scientific context, to show us the evolutionary reason behind it… This is a delectable display for all who love the stamping-ground between pop and hardcore science penmanship.

Neuroscientist Robert Provine turns an evolutionary lens on the whole shooting match from the corpulent to the faintly improper. Burping and farting were labyrinthine associated with in the unfolding of speech, says Provine. Taking examples from his own research, some of which involved everything more complicated than stalking graduate students and observing how and when they laugh, he explains the origins of some of the most prevalent, but often overlooked, sensitive behaviors.

These embrace yawning, laughing, crying, tears, coughing, sneezing, hiccupping, vomiting and nausea, tickling, itching and scratching, farting and belching, and finally prenatal management.

Even if we aren't tired, why do we yawn if someone else does? Experts at the University of Nottingham have published research that suggests the human propensity for contagious yawning is triggered automatically by primitive reflexes in the primary motor cortex -- an area of the brain responsible for motor function.

Their study -- 'A neural basis for contagious yawning' -- has been published in the academic journal Current Biology. It is another stage in their research into the underlying biology of neuropsychiatric disorders and their search for new methods of treatment. Their latest findings show that our ability to resist yawning when someone else near us yawns is limited. And our urge to yawn is increased if we are instructed to resist yawning.

But, no matter how hard we try to stifle a yawn, it might change how we yawn but it won't alter our propensity to yawn. Importantly, they have discovered that the urge to yawn -- our propensity for contagious yawning -- is individual to each one of us.

Contagious yawning is triggered involuntarily when we observe another person yawn -- it is a common form of echophenomena -- the automatic imitation of another's words echolalia or actions echopraxia. And it's not just humans who have a propensity for contagious yawning -- chimpanzees and dogs do it too.

The neural basis for echophenomena is unknown.

Shouting in the street? Call the police. Every time. If you're legitimately concerned, they'd rather get a false call than never know.

#6 VALERIA:
I feel like this video is really missing gay/trans slurs. it is true that we don't have the equivalent of 'whore for men, but i feel that that's mostly due to the fact that men are usually insulted through gay slurs.

I am negative. But if I had even been tested and found positive, I could not ever put anyone else at risk. I lost a step-brother to AIDS.

#10 LAKEISHA:
For a long time from when I became sexually active, I used a subdermal implant as a form of birth control. Unfortunately, this completely neutered me; killed my sex drive, stunted my sexuality, made me feel more like a potato than a human. Beginning of last year, I switched to a progestogen-only contraceptive, one that doesn't regulate my hormones at all. Since then I've rediscovered my sexuality/gender identity, and my husband and I are more intimate than ever.
