In fact, American men now rank ninth and women 15th in average height, having fallen short of many other European nations.

Rarely is a beauty standard so explicit and clearly defined, yet Gibson based the iconic illustrations on “thousands of American girls.” This ideal of femininity was depicted as slender and tall, albeit with a “voluptuous” bust and wide hips. The incongruous and exaggerated look was achieved by way of corseting, pinching the torso and waist significantly.

Gibson Girls were portrayed as up-to-date on fashion and style, as well as physically active and in good health. Adult Eating Disorders: Anorexia, Bulimia, Compulsive Eating, and More. Kenji Toma Usually she just had a cup or two of plain pasta.

Human Oddities

Your Very Weird, Very Personal Sense of Smell. We’re used to the idea that some among us are colorblind, perceiving the world differently because of a quirk in their genetics.

Your Very Weird, Very Personal Sense of Smell

And it’s well-known that teenagers and young adults can hear high-pitched sounds that their elders cannot, an ability that’s been exploited by manufacturers of The Mosquito, an anti-loitering device that annoys youth into leaving. But perhaps because the effects are harder to compare easily, or perhaps because we have such a hard time talking about them, we tend to overlook some rather peculiar differences in our senses of smell. When people get a whiff of a molecule called androstenone, they may say it smells like sandalwood, or vanilla—or they might say it has a sickening, urine-like tang.

Or they might think it entirely odorless. There are around a dozen known chemicals that provoke this kind of disagreement, scientists think.

Could Humans Walk on Water? For centuries, humans have floated the idea that we might, one day, walk on water. In the 15th century, Leonardo da Vinci invented a pair of pontoon-like shoes intended for this purpose, and in 1988, French entertainer Remy Bricka walked across the Atlantic on a pair of floating skis. Perhaps we were inspired by nature more than 1,200 species of animals can walk on water . The smaller ones, such as insects and spiders, use surface tension, the force that holds water molecules together , to support their weight. These forces are much too weak to support the weight of larger water walkers, such as the basilisk lizard, which generates force to stay afloat by slapping its feet on the water.

Odd Gender Differences Found in Walking. If we see a shadowy figure walking down a dark street, our sense of whether it is coming at us or walking away depends on whether we see it as a he or a she, new research finds.
