2.11. CVA = cerebral vascular accident; stroke

Blood, like human emotion, doesn't do well when blocked or overflowing everywhere. Most people still use the term, "stroke," for the third leading cause of death in the U.S. (after heart disease & cancer), though for awhile the National Institutes of Health (NIH) was trying to make the phrase, "brain attack," happen.

During a heart attack, part of the heart doesn't get enough blood/oxygen, starts freaking out, and cells might die. When a brain attack or stroke happens, part(s) of the brain don't get enough blood/oxygen, or maybe a blood vessel ruptures. Either way, call an ambulance, because time = brain cells.

If someone exhibits sudden numbness/weakness of the face, arm or leg, esp. on one side; experiences sudden confusion; suddenly has trouble speaking or understanding; has a sudden severe headache with no known cause; suddenly has trouble seeing in one or both eyes; or has sudden trouble with walking or balance, call 911 immediately (as opposed to driving a private vehicle, as paramedics can provide rapid, first response upon arrival).

Do not let the patient dismiss his or her symptoms, go to sleep, take an aspirin or other blood thinner (this can make a brain bleed worse), or eat/drink (patient may choke). There are transient/mini strokes as well as acute strokes, and these could be due to a blocked or ruptured blood vessel--the only way to confirm a blockage or bleed is through a CT scan at the hospital.

In the ER, the patient will receive a CT scan or MRI, an electrocardiogram (ECG), bloodwork and other tests. A diagnosed clot may be treated with a "clotbuster," while a bleeding vessel or aneurysm should be embolized (blocked).

After discharge, patients may need rehabilitation or additional care due to temporary or permanent deficits. If the left hemisphere of the brain is damaged, there may be deficits in logic, ability to understand language, and changes in mobility on the right side of the body. If the right brain is damaged, the patient may show poor impulse control, balance, and issues with the left side of the body. The good news is the faster initial stroke symptoms were spotted and responded to, the better the patient's chances of positive outcomes.

Our hearts may pump blood and oxygen to every part of the body, but our brains make us who we are--perhaps a good reason to take good care of those precious brain cells.

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 …
