Yes, smoke alarms are very important and save lives all over the place. If you haven't got one you should. Go and buy one immediately.

Right now the sensible, moral disclaimer bit is out of the way, I can get on with telling you about my hair brain ponderance. I stayed at my parents this weekend and was shocked out of my sleep at 5'o'clock Saturday morning by my Dad burning toast. It was quite a shock and it took about 15 minutes before my heart rate was back to normal. It was in these 15 minutes that I began to wonder, had anyone ever died of a heart attack due to someone burning toast? Are smoke alarms in fact a stealth killer of the elderly and weak hearted?
I've known some flippant smoke alarms in my time that would go off if someone breathed too heavily. My boyfriend used to live in a house where the smoke alarm was always going off due to his housemates' middle of the night cuisine endeavours. Maybe all these smoke alarm wake up called have toughened my resolve and I now have the heart of an ox and nerves of steel. Then again maybe I'll babbling and is impossible for a smoke alarm to cause a heart attack.

**If you think there is any reason in this theory and in fear of a heart attack, you go home and take down your smoke alarm, you are an idiot, and I take no responsibility when your house burns down.**
