As time passes, we slowly but steadily learn what's in the bill. By 2014, all health care records will be in electronic form. Presumably the job of converting all that data into electronic format will be given to a union based company who will farm the job out to the Chinese.
If you want to know what's in your record, and the U.S. server is down, you will be able to get your records from the Great Wall Software Services Co. in China.
Of course anyone else will also, so expect your e-mail spam to begin including snake-oil remedies tailored specifically to your ailments. Since your body mass index is in there too, expect a lot of weight-loss junk along with.
My approach is to have my doctor enter me as a new patient with no past history into the new database. That way I have no pre-existing conditions, and the Chinese have no useful information. BMI is a calculation based on your height squared divided by your weight, plus a bit of a fudge factor. At 5'8" and 170 pounds, my BMI is 25.8, and I'm considered a bit overweight. The obvious solution is to enter your height in hands, and your weight in stones. This will get you down a couple of points, and might make the difference in the decision to cut off your food allocation.
