 Question: can you have a heart attack from laughing Context: Tara realizes that A History of Witchcraft is missing from their shelf and after concluding that Dawn took it, she and Willow (who is sheepishly feigning surprise) decide to call Buffy. Buffy hears about Dawn's spell just as she is finishing it upstairs in her room. When Buffy confronts her, the two girls get into a vicious argument about their different ways of dealing with their mother's death. Dawn accuses Buffy of being so busy arranging everything that she doesn't care that their mother is dead, earning herself a slap across the face from her sister. Buffy immediately regrets her action and admits that she's keeping busy so she doesn't have to deal with the situation, because when she stops then her mother is really gone. During their argument, a figure emerges from Joyce's grave and walks toward the house. A shadow passes by the front window followed by a knocking on the door, and Buffy, hoping it's Joyce, rushes to answer the door. Dawn immediately realizes the inherent dangers of the spell and rips up the photo, and when Buffy answers the door all she finds is an empty step. This is too much for Buffy and she starts to cry, finally facing the reality of her mother's death. A sobbing Dawn hugs her, and they collapse to the floor united in grief.
 Question: does buffy's mom come back to life Context: The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. The brain and spinal cord together make up the central nervous system (CNS). In humans, the spinal cord begins at the occipital bone where it passes through the foramen magnum, and meets and enters the spinal canal at the beginning of the cervical vertebrae. The spinal cord extends down to between the first and second lumbar vertebrae where it ends. The enclosing bony vertebral column protects the relatively shorter spinal cord. It is around 45 cm (18 in) in men and around 43 cm (17 in) long in women. Also, the spinal cord has a varying width, ranging from 13 mm (⁄ in) thick in the cervical and lumbar regions to 6.4 mm (⁄ in) thick in the thoracic area.
 Question: is the spinal cord part of the brain Context: In baseball, the designated hitter rule is the common name for Major League Baseball Rule 5.11, adopted by the American League in 1973. The rule allows teams to have one player, known as the designated hitter (abbreviated DH), to bat in place of the pitcher. Since 1973, most collegiate, amateur, and professional leagues have adopted the rule or some variant. MLB's National League and Nippon Professional Baseball's Central League are the most prominent professional leagues that do not use a designated hitter.
