Ok my friend and I were discussing ???

[Love is a Pit Bull !]

Me and my friend were discussing heart attacks and heart disease. Well she said that only "obese" people have heart attacks and that since im more laid back, Im less likely to have a heart attack even though im overweight.

Is it true that just because im less stress I couldn't have a heart attack ? I don't necessarily believe it's true because anyone can have a heart attack..
