Springing Ahead & Falling Back every year causes heart attacks to spike, sleep problems increasing road accidents, reinforces seasonal & non-seasonal depression for millions of people, & is harder on farm animals. This precipitates numerous deaths, many injuries & disabilities, significant loss in productivity, & significant property damage.
Simply abolishing Daylight Saving Time would not help with, and may well exacerbate, seasonal & non-seasonal depression & co-morbid conditions, which debilitate millions of Americans of all ages, classes, backgrounds, regions, & professions.
America should indeed stop changing clocks back and forth, but make DST year-round & permanent, period. "Set it and Forget it."
