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.
But Lincoln had one problem: the United States Constitution. Lincoln was not the first president who wanted to achieve an objective that did not come within the scope of his constitutional powers. The Constitution protected slavery by leaving it in the control of the states. It gave the president no power to free the slaves.
