Note: After several levels of Doom, played in the dark, it is a bad idea to go outside for a smoke and not turn on a light.
This is because when a large creature crashes through the bushes at the end of your yard and pounds across the grass, your first reaction is not OMGDEER but HOLYFUCKDEMON, and you reach for the BFG you do not carry.
Second note: If it had been a HOLYFUCKDEMON, and not a deer, you would not have killed it by flinging your lighter and shrieking like a girl.
Context knows those things can kill you - they just never specified how.
