 Question: can you have a heart attack from laughing Context: The polar bear (Ursus maritimus) is a hypercarnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is a large bear, approximately the same size as the omnivorous Kodiak bear (Ursus arctos middendorffi). A boar (adult male) weighs around 350--700 kg (772--1,543 lb), while a sow (adult female) is about half that size. Although it is the sister species of the brown bear, it has evolved to occupy a narrower ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice and open water, and for hunting seals, which make up most of its diet. Although most polar bears are born on land, they spend most of their time on the sea ice. Their scientific name means ``maritime bear'' and derives from this fact. Polar bears hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present. Because of their dependence on the sea ice, polar bears are classified as marine mammals.
 Question: do polar bears live in the arctic circle Context: When Eli leaves, stating he'll be outside, Tara calls for Wayne, assuming his truck outside meant he was in the house. Caught off guard, Gemma comes out of the laundry room and lunges for Tara, who cannot escape in time. Gemma hits her with an iron but doesn't knock her out. Tara struggles against Gemma's beating and her head is badly smashed on the sink, where Gemma then attempts to drown her. In one of the show's most gruesome moments, Tara struggles for several seconds before Gemma grabs a barbecue fork and stabs Tara multiple times in the back of the head and her neck. Blood gushing out of the back of her head, Tara collapses and dies.
