All good ideas Rocket and it reminded me of a good tip my mom (who works at a hospital and says it has been helpful in the past) guilted me into doing. Having a entry in your cell phone book labeled "ICE" (for "in case of emergency") who is someone who knows your blood type, allergies, medical history, medications etc. A weight free way to improve your medical safety and way more likely to save your life than a band-aid.
