YSK that the iPhone has medical information accessible by holding the lock button (or lock+volume down for iPhone X) which contains the identity of the phone owner, medications they take, known conditions, allergies, and organ donor information

I thought it might be a good idea to post this info after reading a thread about a trauma surgeon who found a lost iPhone and didn't know about this feature.

Also for those of you who have an iPhone and haven't set up your Medical ID, you can do so in the Apple Health app.
