hepatic = everything liver

Like a starfish or lizard, the liver can regenerate. A severed liver won't grow itself a whole new human, but as long as 25% of it is still there, a healthy quarter-liver can grow back to its original size. 

Ancient Greek physicians talked about yellow and black bile, respectively associated with fire and earth, passion and prudence.

Chinese medicine associates the liver with the element of wood, the emotion of anger, and ying chi.

The liver may not be imbued with emotions in these anthropomorphic manners, but when it falls ill, blood won't clot, skin turns yellow, the body swells from water retention, and the brain's poisoned with ammonia.

This sleek, brown sponge separates specific compounds from blood in the body, filtering hormones, alcohol, and drugs. To the best of its abilities, it does a first pass of everything we take in, the therapeutic and toxic. 

Like a moist, leather satchel, the liver also stores important molecules: glycogen; vitamins A, D, E, K, B12; iron; and copper. This hepatic purse holds the currency of life.

In addition to filtration and storage, the liver makes useful substances. Bile helps digest protein, carbs and fat, making the synthesis of clotting factors possible. Albumin keeps fluids inside the blood vessels rather than outside, in swelling skin and flesh. Angiotensin, activated by renin, raises blood pressure through narrowing blood vessels.

Once one's liver has been scarred all over by hepatitis, chronic alcoholism, or cancer, however, there's no going back. Hepatic disease is one of the worst ways to go, long & confusing, weighed down with visceral pain. 

So try not to poison that slippery slab of hepatocytes too much--it has one's back in so many ways.

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 …
