Some burglaries are done by kicking your front door in at gunpoint with your kids screaming in the next room while they threaten to rape your wife if you don't open the safe. If you don't want to get robbed you lock our doors and windows, set your alarm, put your lights on timers, don't advertise when you're going on vacation to the whole bar, etc etc etc. You take precautions so that preventable stuff doesn't happen! You don't want a heart attack, so you eat well, exercise, quit smoking, cut down on alcohol, try to reduce stress- but at the end of the day if you have a condition there's nothing you can do about it. That doesn't mean that you don't have to bother reducing the hundreds of other things that could give you a heart attack! Fats are so stupid.
