Putting an end to Daylight Savings Time

I believe, as a country, we should put an end to this ridiculous practice of Daylight Savings Time. Switching the time back and forth twice a year is, at best, inconvenient - at worst, deadly. As a former clinical researcher, I feel certain that a review of the appropriate records would support my suspicion that this change, particularly in the spring, is responsible for accidents of all kinds that could be avoided otherwise. I am speaking particularly about hospital errors and traffic accidents, but any activity that requires alertness and accuracy is at risk of being compromised by citizens who are sleep-deprived and groggy for the days or weeks it takes to readjust their biological clocks. Pity the students as well, who are coming to the end of their school semester and must readjust their bodies at a critical point in their school year. As humans, we all have biorhythms and this practice is a ridiculous disservice to our general health. I would prefer that we remain on the "natural" time year-round, but would settle for either schedule if we would just stick to one of them.
