I finally bought a ROAD iD wristband about 30 minutes ago. It's one of those medical emergency bands that you put on your wrist to show your name (in my case, my first and last name, plus middle initial), DOB, emergency contacts, and meds/allergies. Since my meds change so much, I just opted to put my allergies (Tylenol and Penicillin).

I do bring my phone with me whenever I go out, but it's nice to have peace of mind. Plus, I know I can get an ID card for cheap and stick it in my wallet, but it's way easier for someone to read and find a wristband than it is to go through someone's wallet searching for info. Plus, most EMTs are actually trained to look for medical ID bracelets.

I suppose it's not overly useful unless you're elderly or active outside all the time, but I think it's good to have, especially since I have been exercising more outdoors in the past 2 weeks.
