Night shift workers who have trouble sleeping may have a condition known as shift work sleep disorder. âWorking non-traditional shifts interferes with the bodyâs circadian rhythms,â says sleep expert Tina Waters, MD. âMost of us are awake during the day because our bodyâs internal clock is keeping us awake.
Election to Congress in 1854 and the Mexican War brought the issue of the expansion of slave territory to the nation's attention. Lincoln formed a clearer position on slavery. He was opposed to black equality and had no intention of disturbing slavery in slave states.
The Wilmot Proviso proposed that any new land acquired from Mexico would have no slavery allowed. This brought back the popular debate over slavery and John Calhoun argued that it violated the 5th amendment since slaves were property.. This divided the nation and brought on the secession and eventually the civil war.
