Is it possible to control what your coach knows about you?
However, it should be possible to control your medical records...
This is BUKU important, since your records determine if you get Health Insurance. ( I know, I know, you believe that in 2014 everybody qualifies. True, but you'll be placed into a state high risk pool, with benefit limitations and narrow access to medical services. That's the "loophole" the insurance companies created.)
Also, having your medical records with you, as you're being driven to the Hospital after a Prop fell on you, will allow the ER physicians and nurses to care for safely and properly.
You will end up paying for your health insurance. Control it by controlling your medical records.
As to the Coach....um, sorry.
