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.
Soon after Lincoln was inaugurated in 1861 the southern states felt that he would attempt to abolish slavery. They decided to seceded from the country, an act which caused the American Civil War. During the war Lincoln threatened to free all the slaves from any state that did not return to the Union.any states outlawed the practice and slaves attempted to escape to these locations. The issue came to a head when Abraham Lincoln, who opposed the spread of slavery, was elected President in 1860.
