 Question: can you have a heart attack from laughing Context: The group keeps searching for Sophia but is unsuccessful. In the episode ``Cherokee Rose'', Carl's injuries ultimately lead the whole group onto Hershel Greene's farm, where they settle. They continue their search, but still nothing seems to turn up. In the episode ``Chupacabra'', the only thing that comes to light is Sophia's doll, which had been discovered by a member of the group named Daryl Dixon. Daryl goes on several searches for Sophia, being one of the most devoted members of the group in looking towards recovering her. He and Carol bond greatly because of his efforts. In the mid-season finale ``Pretty Much Dead Already'', Glenn tells the group that he discovered that Hershel has been keeping a group of walkers, consisting largely of his family and neighbors, in his barn, as he had believed them to be sick but nonetheless curable patients. Shane goes against Rick's orders, opens the barn, and (along with the rest of the group) shoots all the walkers that stumble out. Just as things seem to be over and done with, one more walker stumbles out of the barn - Sophia, who had been bitten while in the woods. (She had then been found by Otis, who put her zombified form in the barn before his death.) Knowing what must be done, Rick steps forward and shoots her, putting her out of her misery. In the mid-season premiere ``Nebraska'', she is buried in a funeral ceremony, alongside Hershel's second wife Annette and stepson Shawn (who were also kept in his barn as walkers). Carol does not attend the funeral because her daughter ``died a long time ago''.
 Question: do they find the little girl in season 2 of walking dead Context: Many newer units employ automatic defrosting (often called ``frost-free'' or ``no frost'') and do not require manual defrosting in normal use. Although, in some cases, users of Frost Free fridge/freezers have noted ice blocking the vent that allows air into the refrigerator compartment. All refrigerators and/or freezers whether or not frost free, should be defrosted at least every 6 months (or more if you live in humid conditions or if the door is opened excessively). Frost Free units should be defrosted every year, as frost can form on the evaporator covers, which can look unsightly and degrades freezing performance, sometimes to the point of the freezer thawing out due to degradation of defrosting. This can happen when the defrost timer is not set up correctly/malfunctioning or if the heater units or temperature sensors are malfunctioning.
 Question: should you defrost a frost free fridge freezer Context: Atrial septal defect (ASD) is a heart defect in which blood flows between the atria (upper chambers) of the heart. Some flow is a normal condition both pre-birth and immediately post-birth via the foramen ovale, however when this does not naturally close after birth it is referred to as a patent (open) foramen ovale (PFO). Normally, after PFO closure, the atria are separated by a dividing wall, the interatrial septum. If this septum is defective or absent, then oxygen-rich blood can flow directly from the left side of the heart to mix with the oxygen-poor blood in the right side of the heart, or vice versa. This can lead to lower-than-normal oxygen levels in the arterial blood that supplies the brain, organs, and tissues. However, an ASD may not produce noticeable signs or symptoms, especially if the defect is small. Also, in terms of health risks, people who have had a cryptogenic stroke are more likely to have a PFO than the general population.
