ARIZONA, OCTOBER 2012
This remarkable photo was taken by Arizona’s Randy Atkins, who is a professional photographer. His wife Alicia gave birth to their daughter Neveah last October.
“The doctor called me over and said, ‘Hey, she’s grabbing my finger,'” Mr Atkins told Arizona’s 3TV News. “So I ran over there and just grabbed the shot and I was just in awe looking at it. It was such an amazing picture.”
The Atkins posted the photo on facebook and thanked obstetrician Dr Allen Sawyer.
By the way, doctors say that it is not unusual for babies in this position to reach out to the world. The story reminds us to an even more impressive story about a 22 week old fetus who made a likewise gesture in the year 1999 (see picture below):

Reflexology is known as an alternative medicine involving ‘zone therapy’, which implicates the physical act of applying pressure to the feet, hands, or ears with specific thumb, finger, and hand techniques without the use of oil or lotion. Last year a study from Iran has pointed out that reflexology can produce significant results for women regarding pain intensity and the duration of labor in primiparous (women who are pregnant for the first time).
Likewise results for pregnant women had been reported from Iran in 2010.
However… it is important to be aware that there is no consensus among reflexologists on how reflexology is supposed to work; a unifying theme is the idea that areas on the foot correspond to areas of the foot, hand and ear, and that by manipulating these one can improve health through one’s qi.
Therefore it could be very well possible that these findings result from the same ‘human touch’ principles that are being used in haptonomy.

Scientific ‘fingerology’ may help you to identifiy your most likely potential for success… or failure via the ratio of only two fingers. What is your 2D:4D digit ratio?
More blogging-reports are available at:
PS. Your digit ratio can be seen as a measure for prenatal testosterone, which explains why this finger-measure correlates with many aspects in life!

The Guardian, Aug 1 – People have started speaking with hashtags. Not often, and not, in most cases, people anyone really likes, but people nonetheless. And the problem – beyond the fact that this is happening at all – is that no one seems to be quite sure how to say, for example, #spokenhashtag.
Abruptly inserting the word “hashtag” mid-sentence just won’t do. It’s far too clunky, like having to shout out “inverted commas!” before and after a suspect sentence, instead of forming a pair of air-quote bunny rabbits.
An “air hashtag” also looks tricky: attempting to draw out the # symbol with a finger takes four time-consuming strokes, and makes you look as if you’ve paused mid-thought to bust out a hand-jive to the imaginary music in your head.
Trying it with two fingers and two quick strokes – one horizontal and one vertical – just looks like an effete mimed raptor attack, while going all-out with two slashes of both hands risks being mistaken for a bizarre attempt at semaphore without flags.
They would all also require you to say “hashtag” while doing them anyway. At least at first, until people caught on.
No, we need standardisation. We need – drumroll please – a hashtag tone of voice. Sarcasm, after all, has one. Why not the humble hashtag? It’s the new gesture-language, and it appears a matter of time before you’ll tweeting fingers everywhere!

Testing. Is it time to stop and scrounge for shelter or is it better to keep trekking? Use this simple trick to measure the remaining daylight. Remember to allow yourself at least two hours to set up camp before the sun goes down.
Count the finger widths between the sun and the horizon. Each finger is equivalent to fifteen minutes, with each hand totaling an hour. When the sun dips low enough that only two hands fit. It’s time to search for a suitable campsite and assemble a shelter.
(A caveat: if you’re near the poles, the sun will hover over the horizon for a longer period of time, giving you an innaccurate reading)

While watching the swimming tournament at the London Summer Olympics, take a good look at the hands of the competitive swimmers! For, new research finds that this hand position creates an “invisible web” of water that gives swimmers more speed. Now, should Michael Phelps improve his ‘finger-techniques’?
Researcher Adrian Bejan, a professor of mechanical engineering at Duke University reports:
“It is a counterintuitive idea, the fact that you should paddle with a fork, not with an oar.”
However, the 2012 study was preceeded by a 2009 study which had already pointed out why most swimmers spread their fingers while swimming (see the picture below – describing how water flow varies for different finger positions).
Webbed feet and hands, of course, are a common trait of swimming animals from frogs to whales. In human swimmers, the invisible web of water allows them not to propel themselves faster, but to better lift themselves out of the water. That’s where the speed comes from, Bejan said. Swimmers push against the water’s surface not unlike South American Lizards, which can scamper on top of water by slapping their big feet against the surface. This force propels the swimmers out of the water, where they then fall forward, generating a horizontal wave.
“The higher you are above the water, the faster you fall forward and you see this effect in greater speed,” Bejan said.
With ideal finger spacing, the forces a swimmer can exert are 53 percent greater than those produced with no finger spacing, Bejan and his colleagues reported online June 9 in the Journal of Theoretical Biology. For aspiring swimmers at home, the perfect spacing is between 0.2 and 0.4 times the diameter of the finger itself.
The findings could have implications for better swimming robots and propulsion systems, Bejan said. They’re also handy for those trying to beat personal bests in the water.
What do you think: should Michael Phelps improve his finger-swimming techniques… in order to make another golden- paddle?
Here’s a fun experiment: stop what you’re doing and use your hands to count to ten. Done? Good. Now remember how you did it, because we’re about to analyze your technique; as it turns out, how you count with your hands may say a lot more about you than you think.
So, how do you count?
Many cultures use some variation of what psychologists call the “closed fist method”, wherein one starts with a closed fist, and begins counting by unfurling the fingers of his or her hand. But the similarities end there.
“The degree of cultural diversity in finger counting… has been grossly underestimated,” write psychologists Andrea Bender and Sieghard Beller in the latest issue of Cognition.

The X-Finger is developed by Dan Didrick (Didrick Medical Inc.) and it has been presented as the world’s first active-function artificial finger assembly designed specifically for partial finger amputees. This finger device provides users to regain complete control of the flexion and extension movements with an artificial finger in a self-contained device. The X-Finger wass designed to bend a silicone finger sheath in a very realistic manner.
Dan Didrick was motivated in part by a desire to help a hearing-impaired person regain sign language ability after losing fingers. He whittled his first concept prototype out of pine wood.
Then he began using 3D design software to refine his landmark invention. Eight years after initial sketches, hundreds of X-Fingers are in use today, and Didrick Medical has also produced X-Thumbs.
It appears that there is a big demand for these simple X-finger devices. Because according U.S. Bureau of Labor data, every year about 8,000 work-related amputations occur involving one or more fingers.

As a research scientist, Dr. Erina Lee is responsible for the international relationships research at eHarmony. In the following article she described how to use hands in building relationships!
Whether they’re soft and manicured, strong and calloused, weathered and wrinkled—hands come in all shapes and sizes and can often say a lot about you. They can reveal the tattered fingernails of nervous nail biter, the orange fingers of a cheese puff lover, or the worn hands of a grandmother. And when you look even closer at the many lines and wrinkles, is it possible that your hands can reveal even more? Some people believe that clues to our basic selves can be found in the details of our hands. But do our hands really tell us anything of importance about who we really are? Is it possible that the numerous bumps and ridges unique to every hand hold some insight into our level of intelligence or into our love lives?
In an eternal quest for self-discovery, people have looked towards hand readers, among other mystics, to see if the lines in their hands really tell them something meaningful about themselves and their future. In current times, people turn to internet quizzes and online hand reading to make sense of the heart and life lines and the shape of their hands. Although these tests and quizes can be fun, when put to the test of empirical science, most of these claims and predictions cannot be verified. Furthermore, these uncorroborated predictions about personality traits and future events leave palm reading in the category of a pseudoscience.
Despite the inaccuracy of palmistry readings, however, there are aspects of the hands that have been studied empirically, including finger length. When looking at the palm of your hand, fingers straight together, you will likely notice a difference between your second (index) and fourth (ring) fingers. On average women have longer index fingers, compared to ring fingers while men have longer ring fingers compared to index fingers. This association between the two fingers, called the 2D:4D ratio, is related to levels of androgen exposure (a sex hormone higher in men) in the womb. That means that the amount of male hormones a fetus is exposed to determines this very specific detail of finger length in the hands. The precise mechanism by which androgen works is not entirely clear, but in general most theorists believe that increasing androgen exposure will masculinize a fetus. There is also some evidence suggesting that either too much or too little androgen can be feminizing to the fetus.
Because androgen exposure is related to sexual development and masculinization, researchers have begun to wonder if the 2D:4D ratio, as a marker of hormone exposure, may also predict other characteristics. Hormone exposure has been linked to things like general physical health, cognitive abilities, personality, job preferences, attractiveness, and sexual orientation. While the 2D:4D ratio may relate to these developmental characteristics, thus far the evidence supporting such a link is at best described as mixed. For example, there has been much attention dedicated to whether the 2D:4D ratio relates to sexual orientation. While there have been several studies in this area, some have shown no differences between heterosexual and homosexual men in their 2D:4D ratios (e.g., Williams et al., 2000), and others, like Lippa, have shown heterosexual men having lower 2D:4D ratios compared to homosexual men. Similarly with other characteristics like personality and attraction, the research findings have been fairly inconsistent.
Another aspect of the hands that have been conclusively studied are the ridges, the ones that cover the palms and fingers, the ones that make up our unique fingerprints. The study of these ridges is called dermatoglyphics. Similar to the finger length, these ridges are known to be established earlier in the embryonic development, while the fetus is still in the womb. Researchers have shown dermatoglyphic differences between non-deficient people and those with cognitive or genetic abnormalities, like schizophrenia, Down’s syndrome, and intellectual disability. For example, individuals diagnosed with schizophrenia show fewer ridges between two specific points under the second and third fingers [a-b ridge count] compared to non-schizophrenic controls (Bramon et al., 2005). These findings support the idea that changes in the prenatal environment can display its effects in multiple ways, including changes in cognitive development and ridges of the hands. However, the findings do not assume that all people with fewer ridges have cognitive deficiencies.
To summarize, we do know that specific details in our hands are affected by early hormonal exposure and other environmental influences in the womb. And we know that this early exposure also affects other aspects of our development. While it is intriguing to speculate further that details in our hands can predict aspects of our personality or behavior, these conjectures have not been empirically supported. It’s also likely that there are more direct measures of personality, intelligence, and behavioral traits rather than the hands. But even though you can’t currently rely on your hands to unlock all of your mysteries, one thing you can count on is more studies and discussion about them to come.

Okay… a funny introduction to John Lajoie’s world!
NOTICE: This video includes some strong language, but be aware… this guy is claiming to have 6 fingers: 5 on his right hand + 1 finger on his left hand – he simply doesn’t count the other 4 – so maybe none of John Lajoie’s words should be taken seriously.
More of John Lajoie’s ‘hands nonsense’ is available here: http://www.jonlajoie.com/aboutme.html
Just in case you’re interested in more serious ‘funny’ reports about hands, you will probably enjoy reading about the international reports about people who have more fingers beyond your imagination:
