I sort of agree with you...we should wear something indicating our condition although I have not done so in ages...
I used to carry a USB key with my whole medical file but you need to find a way to tell the doctors in ER in need be (hopefully you never need it) to check the key...a keychain with a data stick is a good idea too...a medic alert is not that useful if they do not know what the k pouch is...(here in Europe they do not know what medic alert is!)...
Some people carry a card in their wallet or purse...you need something that tranquilizes you and gives you reassurance that they will know what they are doing in the case of an emergency.
