Sounds very valuable. What pieces of information would you be most interested in? Are you hoping to learn things from the information or just have it accessible for when you might need it?
By the way, I work at PatientBank, where we could certainly help you request your medical records (for you and your family). Though we haven't done much to make the experience of viewing/structuring your records that helpful (thus my questions). Would be very interested in your insight. Thanks!
