2.13. H2O = water

Some say amniotic fluid smells like sea foam, or forest loam. Life came from the sea, depends on it, and ultimately, will return to it. Human bodies are more than 60% water, and the blood coursing through arteries and veins, more than 50% H2O.
However, too much water can drown us from the outside, or inside. Every year, newborns die from water intoxication (from extreme electrolyte imbalance) because of adults diluting canned formula in an attempt to make it stretch several times too far. Kids drown in the deep end of pools, or, having gasped water into their lungs, suffer from secondary drowning hours after a close call at the beach. Sorority and fraternity pledges also die from water poisoning days after hazing events involving water-chugging + excessive exercise.

Water may be safer than alcohol, but not when so much is consumed that excessive loss occurs of sodium, potassium, magnesium and calcium, all important to keeping the heart, brain, and lungs functioning. Fluid and electrolyte balances, especially in the very young and very old, can become severe and sometimes fatal. Low or high potassium, calcium or magnesium levels in the body can lead to dysrhythmias or even cardiac arrest.  Seizures may occur with low calcium, magnesium, or sodium, while magnesium toxicity can slow breathing and drop blood pressure. Cerebral edema resulting from critically low sodium can lead to brain damage, coma, or death.

The balance of lytes, controlled by the kidneys and hormones like ADH, is like the ebb and flow of the sea, coming and going in cycles to maintain homeostasis that is consistent with life. May the waves roll on.

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 …
