A while back xkcd described the up-goer five (a rocket) using only the most common 1,000 words (AKA ten hundred words) in the English language. We now have an Up-Goer Five text editorthat forces you to do the same thing. Here is my description of Pediatric Nephrology using only the most common ten hundred words:
I am a doctor who takes care of children with problems with their parts that clean bad stuff from their bodies. Sometimes we can fix their problems. Other times we have to clean their blood of bad stuff. Sometimes we put a new blood cleaner part in them.
Blood cleaner parts are very important if you want to live.
Wow. I somehow knew "kidney" would not be on the list. "Disease, disorder"...it took a bit to come up with problem(s). Turns out "alive" didn't make the top ten hundred either.
Urine, pee, piss, whiz...nope.
Makes transplantation sound simple, though.
