2.14. RBC = red blood cell

If one has more red blood cells in one's blood, does that make one somehow more red/warm, more capable of love? If one has fewer, does it make one colder, and care less?

No, of course not. An abnormally high number of red blood cells may make one look flushed, but these blood elements have nothing to do with feelings. Red blood cells, aka erythrocytes, through their hundreds of thousands of hemoglobin molecules, carry 4 molecules of oxygen per hemoglobin molecule, everywhere in the body. This makes the basic metabolism that enables life possible. Too little or too many red blood cells are not good. Neither are abnormally shaped ones.

Low red blood cells = anemia, which could be caused by blood loss, low production, or destruction. To help with deficiency-related production problems, one may increase intake of iron, folic acid, or vitamin B12. If low levels are related to a condition, such as pregnancy or Crohn's disease, treatment may or may not exist or be necessary. Same goes for destruction of blood cells occuring through infection, medication side effects, or disorders/disease.

If one has a higher than normal percentage of red blood cells, this may be due to 1) being a baby, 2) blood doping, or 3) disorder/disease. Babies grow extra red blood cells to help their adorable bodies get much needed oxygen. Olympians may train at a high altitude, where oxygen is more scarce, to force their bodies to produce more red blood cells that will improve their endurance, or they may transfuse extra red blood cells into their circulation for the same effect (and lie about it). A particularly ruddy-cheeked patient may have rubra vera, a condition where the body overproduces blood cells ranging from red to white to platelets. Too many of these cells will clog arteries just like excess glucose or cholesterol. In some conditions, red blood cells are even known to form rouleaux, stacking together like a roll of quarters.

Sickling is bad in ballet and worse in red blood cells. When the cells sickle, they can't do their job of oxygen delivery. Something that's supposed to look like a donut shouldn't shrivel into a crescent moon, because then the moons will get stuck in blood vessels and cause damage. Also, no oxygen.

Erythrocytic homeostasis: make donuts, not croissants; make just enough, not too many or not enough.

  1. Ever since my autoimmune disorder dx, my red blood cell count has been consistently above the normal range. My rheumatologist isn't too worried about it though.

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 …
