Medical alert jewelry
This is a new comment on an old question on this site: should you wear a medical alert bracelet to tip off strangers in case of an emergency?
Of course. Why not? I consulted with EMTs in my city and they also advised against using charms and decorative pendants with that item because it can then resemble jewelry rather than medical info.
Mine states coumadin, pacemaker, my name, my daughter's contact and the name of the hospital that has my records. It is visible but not over-bearing, and I consider it to be extra insurance for my life.
Why wouldn't someone do this? It makes sense. It's just one more item of self-preservation.
