Is that this a paid topic or did you modify it yourself? Anyway stay up the excellent high quality writing, it is rare to see a nice weblog like this one these days..

But if I get your meaning, that effect would be the reverse of what's being reported. If heart attacks came in at a flat hourly rate, then the switch to DST would reduce the number of hours and thus reduce the number of reported heart attacks. Alternatively you could be suggesting that the true rate is actually higher than 5% for the switch to DST as that was 5% over and above a 1/24th shorter day. While that could be true, it would be true only for that day. The report mentioned that heart attacks were at an elevated level for the week following the switch to DST and at a reduced level for the week following the switch back. (I modeled that above as a linear function.) So again, if the simple change in day-length were the cause that wouldn't explain why the there was an elevated risk the day after the change to DST. A graph of the actual data may reveal this bias, of course, it'd be interesting to see a similar graph for heart attack by hour of the day. Hi Joshua:

Funny how 1/24th is about 5%.
