2.9. HTN = hypertension, high blood pressure

A little tension in life keeps things interesting, but if the pressure increases too much, something (like a blood vessel, or relationship,) might blow up.
A base level of stress improves focus, while too much stress leads to tunnel vision and helplessness. Hypertension in the brain can cause problems with memory and understanding (due to reduced blood flow to brain cells), an aneurysm (localized enlargement of artery), or dementia (from chronic lack of blood flow to the brain).

The sympathetic nervous system dilates pupils so one can see better in a dangerous situation, but long term hypertension will damage blood vessels behind the eyes and lead to vision problems.

Our hearts beat faster and circulate more blood when we're excited, aroused, etc., nothing wrong with that, but if that tension persists, the hardworking left ventricle might grow thick and ineffective, and eventually fail. Damage and inflammation in arteries from high blood pressure can also lead to a heart attack or stroke when there's extra damage/blockage to a vessel and a clot forms.

Blood goes Down There when something fun is about to happen (or in progress), but the narrowed blood vessels from hypertension makes it harder for blood to reach the important cells and help them engorge, lubricate, etc. Sure, reproduction's overrated, but...sadness.

Hypertension even wants your bones. High blood pressure causes the body to eliminate more calcium (since hypertension kills the kidneys as well), which can lead to osteoporosis (bones with pores, brittle bones).

We could continue, but it's too depressing. Metabolic syndrome, type II diabetes, end stage renal disease, nonalcoholic end stage liver disease, even cancer due to oxidative stress could all be traced back to high blood pressure. This is the unfortunate, systemic, domino effect that eventually leads to some very fine people showing up in the hospital, getting complete blood counts and metabolic panels done on large vials of their blood drawn daily, and getting heart surgery/dialysis.

So how can we prevent hypertension? It's actually straightforward: diet and exercise. Eat less sodium and fat (e.g. fast food). Eat or drink vegetables & fruit! Walk, run; do taekwondo!

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 …
