Ouch: Why getting kicked “there” hurts so much …

August 8, 2012

One of the America’s Got Talent quarter-finalists this year was a nasty guy named Horse.

His talent: an ability (and willingness) to take repeated shots to the  family jewels.

Fortunately, Horse didn’t pass through to the semi-finals.

But, he got me wondering …

Why does it hurt so much?

Here’s the scientific explanation.

Excerpted from mentalfloss.com

More than any other bodily injury, getting hit in the family jewels is probably what every man dreads most … of all the spots on the human body, none register the same kind of incapacitating, end-of-the-world pain .

What causes such inconceivable pain?

Well, for starters, because of nerves, it’s gonna hurt.

Unlike most other parts of your body, though, the scrotum lacks protection in the form of bones, large muscle mass, and fat …. it   absorbs the whole force of the blow all on its own.

Second, the groin has a ridiculously high number of sensory nerve endings, and such generous innervation makes good and bad touches alike very “noticeable” sensations.

And the pain doesn’t just stay down there …  It  radiates throughout the groin and up into the abdomen (and, psychically, out to every other dude standing within a few feet), leading to a weird stomach ache.

This is the work of a phenomenon known as referred pain, which is when a sensation originating at one spot travels along a nerve root to other parts of the body and is perceived as happening there, too.

The pain starts in the groin and travels up the perineal and pudendal nerves and the spermatic plexus … to the abdomen and  around the spine.

Design flaw ?

Why is such a sensitive and delicate body part just hanging there in the open?

The placement of the testicles is inconvenient, but absolutely necessary.

The testes’ job is to produce sperm, and sperm are very fragile. They’re extremely sensitive to high and low temperatures, and must be kept away from the rest of the body.

They can handle human body temps for only one to four hours, or the average amount of time it takes them to travel through the female reproductive tract and fertilize an egg.

Internal testes or any type of significant shielding for them would heat them up too much, too early and make them drop out of the race well before reaching the egg, rendering them useless.

Ken’s Take: (1) OUCH !  (2) Compelling proof that god is a woman.

From the pollsters’ lips to the teleprompter’s ears (and candidate’s lips) … but, what about the forest?

My students know that, at heart,  I’m a quant guy and encourage market research over gut feel.

So, I should salivate over the Obama campaigns reliance on market research, data mining, and precision messaging.

Excerpted from WSJ

The Obama campaign has elevated poll-testing and focus-grouping to near-clinical heights.

The results from his vaunted focus groups  drive the president’s every action: his policies, his campaign venues, his targeted demographics, his messaging.

More specifically, spotted an interesting analysis in The Hill:

Recent campaign spending records of the Obama campaign, disclosed that they’ve spent $15 million on polling since the first of the year.

Based on typical polling rate card, $15 million for polls translate to about 6 million minutes of polling time.

Assuming interview lengths of 10 minutes, that’s like 600,000 interviews.

Of course, “polling” doesn’t necessarily mean one-on-one interviewing.

Perhaps as much as a third of the $15 million may have been spent on focus groups and ad testing with dials.

Again, using normal rate cards,  upwards of 4,000 Americans may have been asked to participate in these test sessions.

Yep, from the pollsters lips to the teleprompter’s ears … to the candidate’s lips … to the voters ears.

So, what’s my beef?

First, lack of “authenticity” … a willingness to say anything to anybody if it polls well … even if it’s not true (e.g. the multiple Pinocchios that the Wash Post gave to the Bain outsourcing riff and the incredible “I spend less than any President since Harry Truman)

Second, a willingness to “tailor” the message to different groups or individuals … i.e. to pander shamelessly.

And, the larger point: losing the forest in the trees …  whipsawing based on minutiae and missing the big picture,

After all, it’s the economy, stupid.
