melanie, you need a sense of humour, need to be able to stand, walk and run for 8-12 hours and able to come back to work the next day do it all over again. You need to equip yourself clinically because some staff (nurses/doctors) dont know what they're doing. And you know that you are suited to ER when after a code blue you tell yourself.........."Wow! that was great!" (even the patient died) goodluck katrinamay
