Seems you idiots worry about some second hand smoke but are not at all concerned with sitting at roadside cafes and inhaling (with your children present) carbon monoxide spewing from cars. I'm so over this "blame the smoker" for everything attitude. Stress also increases blood pressure too, so does eating fatty food (you don't have to be obese). I believe this article is written with predjudice and is nothing more than a research done and with results skewed so as to recieve more funding.
