 Question: can you have a heart attack from laughing Context: In early March, Jekyll's butler, Mr. Poole, visits Utterson and says Jekyll has secluded himself in his laboratory for weeks. Utterson and Poole break into the laboratory, where they find Hyde wearing Jekyll's clothes and apparently dead from suicide. They find a letter from Jekyll to Utterson. Utterson reads Lanyon's letter, then Jekyll's. Lanyon's letter reveals his deterioration resulted from the shock of seeing Hyde drink a serum that turned him into Jekyll. Jekyll's letter explains that he had indulged in unstated vices and feared discovery. He found a way to transform himself and thereby indulge his vices without fear of detection. Jekyll's transformed personality, Hyde, was evil, self-indulgent, and uncaring to anyone but himself. Initially, Jekyll controlled the transformations with the serum, but one night in August, he became Hyde involuntarily in his sleep.
 Question: was dr. jekyll and mr. hyde the same person Context: The Pittsburgh Steelers (6--2) have won the most Super Bowls with six championships, while the New England Patriots (5--5), the Dallas Cowboys (5--3), and the San Francisco 49ers (5--1) have five wins. New England has the most Super Bowl appearances with ten, while the Buffalo Bills (0--4) have the most consecutive appearances with four (all losses) from 1990 to 1993. The Miami Dolphins are the only other team to have at least three consecutive appearances: 1972--1974. The Denver Broncos (3--5) and Patriots have each lost a record five Super Bowls. The Minnesota Vikings (0--4) and the Bills have lost four. The record for consecutive wins is two and is shared by seven franchises: the Green Bay Packers (1966--1967), the Miami Dolphins (1972--1973), the Pittsburgh Steelers (1974--1975 and 1978--1979, the only team to accomplish this feat twice), the San Francisco 49ers (1988--1989), the Dallas Cowboys (1992--1993), the Denver Broncos (1997--1998), and the New England Patriots (2003--2004). Among those, Dallas (1992--1993; 1995) and New England (2001; 2003--2004) are the only teams to win three out of four consecutive Super Bowls. The 1972 Dolphins capped off the only perfect season in NFL history with their victory in Super Bowl VII. The only team with multiple Super Bowl appearances and no losses is the Baltimore Ravens, who in winning Super Bowl XLVII defeated and replaced the 49ers in that position. Four current NFL teams have never appeared in a Super Bowl, including franchise relocations and renaming: the Cleveland Browns, Detroit Lions, Jacksonville Jaguars, and Houston Texans, though both the Browns (1964) and Lions (1957) had won NFL championship games prior to the creation of the Super Bowl.
 Question: have the buffalo bills ever won a super bowl Context: To maintain lactation, a dairy cow must be bred and produce calves. Depending on market conditions, the cow may be bred with a ``dairy bull'' or a ``beef bull.'' Female calves (heifers) with dairy breeding may be kept as replacement cows for the dairy herd. If a replacement cow turns out to be a substandard producer of milk, she then goes to market and can be slaughtered for beef. Male calves can either be used later as a breeding bull or sold and used for veal or beef. Dairy farmers usually begin breeding or artificially inseminating heifers around 13 months of age. A cow's gestation period is approximately nine months. Newborn calves are removed from their mothers quickly, usually within three days, as the mother/calf bond intensifies over time and delayed separation can cause extreme stress on both cow and calf.
