3.11. Sign = objective evidence of disease

According to Saussure, a "sign" is a combination of signifier (what we perceive) and signified (the meaning we make of what's perceived).
In medicine, a "sign" is objective evidence of a disease (blood pressure 150/100 mmHg) as opposed to a "symptom," (headache) only perceivable by the patient. The signs & symptoms indicate a disease process or differential diagnosis.

Here are some signs that may or may not come in handy one day.

Auspitz sign: if you pick off a patch of your own scaly skin (why?) and see pin point bleeding underneath, it's psoriasis.

Brudzinski's sign: when my mother was dying from meningitis and someone pushed on her neck to bend it upwards, her knees would bend too, helping confirm the diagnosis.

Blumbergs sign: tender pain after a doctor presses on the abdomen then lets go. Possible peritonitis.

Cardinal signs of choking: inability to speak, cyanosis, & collapse. (If you ask, "Are you choking?" and there's no answer and the person turn blue and falls, yes, that person's probably choking.)

Chvostek's sign: tap in front of of the ear and the patient's facial muscles twitch? Low calcium levels in the blood. Very dangerous because changes in heart rhythm and seizures may be forthcoming.

Cullen's sign: if there's blue-ish discoloration in the umbilical area, this might be pancreatitis.

Herman’s Sign: red and purple rash on upper and lower extremities--with other symptoms, could be Dengue fever (Damn mosquitos.)

Kehr's Sign: abdominal pain radiating to the left shoulder? Maybe a ruptured spleen.

Kernig's sign: back to my mother. Additional evidence of her meningitis (if she were still conscious) would be inability to bend the knees more than 90 degrees without overwhelming pain.

McBurney's Sign: some mean person pushing down on the right lower part of the abdomen = pain & tenderness? Might be appendicitis. Who needs an appendix, anyway?

Murphy's sign: another mean person pushing on the gallbladder and it hurts? Possible cholecystitis (inflammation of the gallbladder--the liver's little green purse). Don't really need the gallbladder, either.

Stokes' sign: nothing to get excited about. Somebody's tumor is compressing the superior vena cava and making the collar feel tight.

Trendelenburg's sign: contralateral side droops because the ipsilateral hip abductors do not stabilize or prevent the droop (English: hips go crooked when standing on one leg), a sign of developmental dysplasia (abnormal growth) of the hip.

Trousseau's sign: spasm of fingers and wrist when a blood pressure cuff is tightened at the upper arm, another sign of low calcium level in the blood.

Turner's sign: grayish-blue coloring on one's flanks--another sign of possible pancreatitis. Maybe go lighter on the booze next time.

3.2. ABO = blood type

In parts of Asia, people don't just consult the zodiac, star signs, and the eight numbers of one's birth (八字). There's an entire culture of personality decoding based on blood type. It all started in 1927 when Takeji Furukawa, a professor at Tokyo Women’s Teacher’s School, shared his research connecting personality traits with blood type. Since then, friends and romantic interests ask if one's A, B, AB, or O, and in Japan, people reportedly get discriminated against at school and work based on their blood type.


Correlation of personality with one's A, B, AB, or O blood has not been supported by many credible studies, but some people take this very seriously. If you know your blood type (and you really should), see if the traits below sound about right.

A: Contrary to the Western concept of a "type A personality," people with type A blood (and antigens) can take a long time doing something when they're not motivated, or finish the same task in a jiffy …

3.10. Crisis = time-limited, disruptive, challenge

Are you in a crisis? According to Erik Erikson, we all are. Erikson divides psychosocial development into eight stages. Each period comes with its own "crisis," which once resolved, yields an appropriate "virtue."

0-1.5 years: Baby learns to trust, or mistrust the world. The former yields hope; the latter does not. Seems like many of us are still working on this one.
1.5-3 years: Toddler's crisis (or rather, Toddler's parents' crisis) involves a battle between autonomy v. shame & doubt. Making it through this stage confirms the child's (free) will. No, _____, this does not mean you always get your way.
3-5 years: The Preschooler may struggle with initiative v. guilt, but "purpose" emerges as a way to make sense of it all (hence the Why? why? Whyyyyyyy? WHHHYYY?s). A little bit of guilt here and there is fine for the developing ego and superego.
5-12 years: The School-age Child feels anxious about industry v. inferiority, ideally striv…

TKD = taekwondo

We interrupt our regular programming of blood, guts and babies to talk about taekwondo, a traditional Korean martial arts form.

Tae = kick/strike with the foot.
The foot as a blade, as hammer, as hook, the blow that knocks someone out, a broom sweeping the enemy down, pushing an intruder to the ground.

Kwon = punch/strike with the hands.
The hands, fist or palm, can be knives, blocks for poles, a punch to the solar plexus, bladed support when one rolls or falls, or a friendly hand to help a competitor back up from the mat.

Do = the art, the way of life.
Like any relationship, one's journey in martial arts has ups and downs. There's a honeymoon period, initial excitement--passion or obsession, even. That may not last, but commitment does. There are milestones but also little bumps, minor or major injuries. Things get in the way of training, but some amazing people also support one along the way. Sometimes one learns to find fun in dressing in full storm-trooper sparring gear on a …
