Our medical system is a wonderful thing, especially when you do not see the same doctor two days in a row. 

If you are helping your mom or dad, or both your parents, and your in-laws and... well, you get the idea. You are helping someone intimately handle their medical situation and at this point you know more about them and their medical history than any doctor about to walk into the room. This is not to say that doctor's don't know the medical history, but our medical system tends to treat the here and now problem (you fell and you have high blood pressure) and not look at the long-term medical needs. Take notes. You should have started taking notes 5 years ago... but I guess you'll catch up, right? You do not have much choice.
