so, as most of you guessed, the safest place to have a heart attack is not in a hospital. in fact, its one of the most dangerous. why? so many people are trained in CPR and there are AED's hung in every public place (try to find it next time you go the the grocery store, i'll bet they have one). it actually matters more on how many people are around to see you go down that relates to how likely you are to survive.
the rank:
best place to have a heart attack - casino, then airport (60% survival) then mall, then hospital (only 20% chance of survival).

its because your usually all alone in your room and the nurse is attending to many patients and only checks in once in a while.

I have some pretty smart readers.
