Well, you guys all know I usually keep my mouth shut, and have very few opinions on anything... ;P
re: doctors - Keep in mind that doctors also use abbreviations that to an untrained person don't make any sense.... I can read prescriptions fine, but I also know the medical jargon. For example, my daughter is on Trileptal 300mg BID (BID meaning twice daily, TID would be Three times daily, PO means "Per Oral", etc.)
re: Handwriting
I agree 100% that handwriting isn't taught like it USED to be. I remember seeing a "little rascals" episode where the kids are sitting in class, and the teacher has them making circles, first clockwise, then counterclockwise, that should touch the top and bottom lines of the paper, and be of an equal roundness. Over and over. That's the kind of stuff that it takes to have good handwriting; is training the brain to make the letters consistantly and properly.
When I was about 19, after I was out of high school, I realized that I couldn't read my own handwriting, and made a conscious effort to improve it. Believe it or not, I did pages and pages of those circles, practiced making my ampersands (&) (can you make one of those consistantly writing?

and then worked on my printing as well.
I'm not saying my handwriting is perfect, by any means... my mother had BEAUTIFUL handwriting, but she came from that generation where it was taught in school, but I'm saying it's legible. It's funny, because now, people with sloppy handwriting comment on how lovely mine is.... lol
Just my 2¢
