if you had parents that smoked when you were growing up - do you smoke? if you have siblings, how many of them smoke? if you have older kids do they smoke?
both of my parents smoked at some point, eventually my mom quit. both my brother and i smoke. i have 2 kids (20 and 9 next month), so far son does not smoke and i think we are in the clear on him starting (fingers crossed!), daughter, only time will tell.
