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.
Although Lincoln clearly hated slavery, he assumed the presidency promising not to interfere with it. During the American Civil War, President Lincoln noted again and again that his purpose in fighting the South was to save the Union, not to free the slaves. But as the war dragged on and more and more slaves from the South fled to the Union Army, Lincoln began to reconsider slavery, and he came under more and more pressure to free the slaves.
