You are about to be buried alive.
You will be sealed in a coffin which will be covered with approximately two feet of dirt. There is no external ventilation. There is no easy means of escape. You will be buried alive, for real. If you have any history of anxiety, claustrophobia, heart disease or breathing difficulties; if you are currently taking any medication for any of these conditions; if you dislike total darkness, confined spaces, forced immobilization, restricted air supply or a sense of forced helplessness in the face of your own mortality; then you are contraindicated for being buried alive.
