What happens during a heart attack?
In a heart attack your heart loses oxygen, and eventually causes necrosis of the best cardiac tissues. This tissue death can result in heart failure and deadly arrhythmia. When the plaque in your heart hardens it explodes and platelets come and prevent further release of the plaque that has exploded. However this clotting can block the artery completely and stop the blood flow to a part of the heart. When the blood stops, flow stops, and so does the oxygen to that part of the heart. Because of the lack of oxygen to keep the muscle going, muscle cells die in the heart.

Why do we close our eyes when we sleep?
It turns out that most humans need their eyes closed to get a good nights sleep. Closing your eyes blocks out visual stimulation. When your eyes are closed, you aren’t distracted by visual input. Closing your eyes protects them from getting bugs and other foreign objects that could be damaging. If you try falling asleep with the light on, you would fall asleep a lot quicker because the light makes your eyes tired so your body’s natural instinct would be to close them.
