the ring of the alarm clock is an environmental stressor. As a result, epinephrine and cortisol (the two stress hormones) will immediately and dramatically shoot up, resulting in an instantenuous sharp rise in blood pressure and heart rate. And this sharp rise in cardiovascular parameters, if the heart is already damaged, can lead to a heart attack. This explains two facts: 1) that heart attacks happen more often on Mondays than other days of the week, and 2) that heart attacks happen more often in the morning, at the time of waking up, than at other times of day:
a long term chronic sleep deprivation may eventually damage your heart to the extent that you are more susceptible to a heart attack. This means that you are more likely to suffer a heart attack, but has no influence on the timing of the heart attack - it is the misalignment between the natural circadian rhythms of your body and the social rhythms imposed via a very harsh stressor - the alarm clock - that determines the timing. Being sleep deprived over many years means you are more likely to have a heart attack, but cannot determine when. Losing just one hour of sleep will certainly have no effect at all.
see Larry's post from last year, where you will find a lot of useful information and links about it. What is important to keep in mind is that DST itself is not the problem - it is the time-changes twice a year that are really troubling.
Even if initially DST saved the economy some energy (and that is questionable), it certainly does not do so any more. And the social cost of traffic accidents and heart attacks is now much greater than any energy savings that theoretically we may save.

Popular Fish, Tilapia, Contains Potentially Dangerous Fatty Acid Combination

probable gene-nutrient connection to coronary heart disease in a specific group of heart disease patients

farm-raised tilapia, as well as farmed catfish, "have several fatty acid characteristics that would generally be considered by the scientific community as detrimental." Tilapia has higher levels of potentially detrimental long-chain omega-6 fatty acids than 80-percent-lean hamburger, doughnuts and even pork bacon, the article says.

tilapia had much higher amounts of omega-6 acids generally and AA specifically than both salmon and trout. Ratios of long-chain omega-6 to long-chain omega-3, AA to EPA respectively, in tilapia averaged about 11:1, compared to much less than 1:1 (indicating more EPA than AA) in both salmon and trout.
probable gene-nutrient connection to coronary heart disease in a specific group of heart disease patients
"The ratio of arachidonic acid (AA) to very long-chain n-3 PUFAs (EPA and DHA) in diets of human beings appears to be an important factor that dictates the anti-inflammatory effects of fish oils," the researchers write. They cite numerous studies, including a recent one that predicts "that changes in arachidonic acid to EPA or DHA ratios shift the balance from pro-inflammatory [agents] to protective chemical mediators ... which are proposed to play a pivotal role in resolving inflammatory response" in the body.
