An idea a day: 20. Follow up to 19, if the blog for patients exist, it can be a centralized database to get personal sickness/injection history for both personal and doctors' use. It is very common to be the patient of serveral clinics/hospitals, the doctors are from different companies and don't know each others, so the current medication, sickness history, allergic reaction, injection history are unknown to those doctors, and as the patients are not professionals, it is normal for them not able to recall every jargans that is applicable on the health of themselves. If we could have a blog that represent a medical history of a patients, and everytime patient see doctor, the doctors (may be serveral different doctors) can access the blog and update the sick history, the kind of medicine doctors give to patients, unnormal reactions etc. This can be a record for later reference. The sick history of a patient can only be accessible only with the permittion of the patient, thus this can keep a privacy to personal particulars.
