ive heard a lot that during World War 2 the US was never invaded (Pearl Harbor does not count since the US was not in the war yet). Well both Guam and the Philippine islands were invaded by the Japanese. If two territories don't count as the US having an invasion then the Aleutian Islands Campaign in Alaska brings an invasion into one of its 50 states.
The word "decimate" comes from the Roman military practice called "decimatio." When a certain unit of the army needed to be punished, usually for things like cowardice or desertion, the soldiers drew lots, and 1 in 10 would be killed without exception.
The expression 'saved by the bell' developed 100+ years ago when people were terrified of being buried alive. Lots of graves had a bell with a string attached on them. The string led through the ground and a hole in the coffin's lid into the coffin. Should the person not have been dead at burial and wake up they would pull the string, the bell would go off and they would be dug up.
Edit: add: There were actually cases when that happened.
Alcohol does not kill brain cells. It slows the production of new brain cells (so abuse of alcohol hampers its processes). Studies show that alcohol in moderation can actually help more brain cells form.
