fate, or free will???

i just saw a movie (the name is irrelevant) about this guy who was hit by a car and the priest at the funeral said he was "taken before his time"... this got me to thinking... what really IS our time??? was the guys "time" supposed to be him as and old man on a deathbed, or was it that EXACT second that he was MEANT to be hit by a car and die??? are we all set by fate to die at a certain time, whether it be natural or murder??? or are we in control of how long we live, and that our actions shape our future??? if i stay inside my house for the rest of my life, will i live to be over 100, or will fate find a way to have a calamity befall my home and kill me??? im curious to see your reactions... are we REALLY in control of our lives, or is every movement, action, and breath already set in stone???
