YSK: Getting hit over the head with a bottle is not like movies and can cause someone to die or have long-term medical problems.
Unlike in the movies, if you are hit over the head with a bottle, it can kill you, and even if you don't die, you can have neurological symptoms for weeks or even long-term (post-concussion syndrome).
Why YSK: people think that they are just knocking someone out when they hit them over the head with a bottle, but actually you risk murdering them or causing them long-term disability.
