This is a good thread. I have previously.. saved a girl from choking, rushed my daughter to the ER with a SEVERE nut allergy, called 911 for accidents, etc but those didnt put ME in danger.
I would probably go into a burning building for my dogs or my horses- depending if I thought there was still a chance to save them.
I would try to save someone from drowning, but never by jumping in- that's goes against everything you're ever taught.
I know CPR and would administer it in a heartbeat.
I am bad with trauma though- motorcycle/car accidents, anything with missing/broken limbs, I don't know what i'd do.
The part that would make me hesitate would be me thinkign if the risk involved me dieing, where my daughter would be left without me. But IF its my family in danger, then all bets are off, I would do anything and everything within my power to help save them.
