To avoid death--be vague about who you are (have aliases, have a twin), be vague about when you were born (have a twin, fudge the birth certificate, have someone else baptized with your name and make sure key events in their lives match yours).

And do important deals on water because ghosts can't cross water. It's why so many ghosts end up trapped on boats.
