what does this mean?

So my daughter has a bit of a cold, but at long last this is no cause for alarm. My mom reassured me that I was at no increased risk for infection (notice how this is all about ME), because, according to data gleaned from the latest little vials sucked out of my body, my white blood cell count is up.

The doctor reported this a few days ago after my latest blood test, but of course, being a complete biology incompetent, the information pretty much meant nothing to me. My white blood cell count is up! Woohoo! Soooo.....what?

WELL, so my mom explained, your white blood cells indicate your ability to fight disease. So a normal white blood cell count means you are as capable as any normal person of fighting off normal colds. This is of course much better than the situation under radiation, where everyone has to be very careful not to expose you to anything because you could get the usual winter cold, then bronchitis, then pneumonia, and then just die. I always thought I did that anyway, but I was only imagining things. Apparently--or at least, so I am told--I never actually did die. The situation under radiation be MIGHT be the real deal, although probably not even then, because I always was a bit of a baby when it came to colds.

Anyway, all this made me realize once again how little I know about anything at all, except maybe Chaucer, and of course even there I'm relying on the highly scientific and unbiased narrative invented by a few scholars with a few sticks of wood they saw recovered out of a 600-year-old building somewhere that weren't rotted quite enough to prevent them from imagining what the original town looked like.

In other words, I don't know doodly squat about much of anything. Including how to spell doodly.

If someone else has an opinion on the meaning and spelling of doodly, I'd much appreciate it if they'd shoot me a line.
