 Question: can you have a heart attack from laughing Context: In 1991 the FA decided that only one replay should be played (starting with the 1991--92 competition). If this game ended in a draw, extra time would be played, followed by penalty kicks if the match was still even. In 1999 it was decided that the semi-finals should be decided in one game, with extra time and penalties used to determine the outcome if the game ended in a draw. Replays are still used in earlier rounds, however, though were eliminated in the quarter-finals in 2016. The last FA Cup Semi-final replay, in 1999, saw Manchester United take on Arsenal at Villa Park. This turned out to become one of the most memorable semi-finals of all time, with Peter Schmeichel saving a last-minute penalty from Dennis Bergkamp and a Ryan Giggs extra time goal deciding the outcome in Manchester United's favour. In 2003 this goal was voted the greatest ever in FA Cup history.
 Question: is there extra time in fa cup semi final Context: The signage for advisory speed limits is not defined by the Vienna Convention on Road Signs and Signals, and is therefore not standardised internationally. The United States uses a small yellow sign under the main warning sign, as well as a standalone variation on the standard speed limit sign, with a yellow background instead of a white one, the words ``speed limit'' omitted and an additional panel stating the type of hazard ahead. Though they list speeds, the U.S. advisory speed signs are classified as warning signs, not regulatory signs, as primary speed signs are. Australia uses a similar design as the U.S. in spite of regulatory speed limit signs being quite different. Germany used a square sign with a blue background and white lettering, similar to the minimum speed limit sign, and New Zealand uses a yellow background with black lettering (similar to the Australian design without the ``km/h'' lettering). The United Kingdom currently uses an oblong white rectangle with black lettering stating ``Max Speed''.
 Question: do you have to follow yellow speed limit signs Context: The dairy cow will produce large amounts of milk in its lifetime. Production levels peak at around 40 to 60 days after calving. Production declines steadily afterwards until milking is stopped at about 10 months. The cow is ``dried off'' for about sixty days before calving again. Within a 12 to 14-month inter-calving cycle, the milking period is about 305 days or 10 months long. Among many variables, certain breeds produce more milk than others within a range of around 6,800 to 17,000 kg (15,000 to 37,500 lbs) of milk per year. The Holstein Friesian is the main breed of dairy cattle in Australia, and said to have the ``world's highest'' productivity, at 10000L of milk per year. The average for a single dairy cow in the US in 2007 was 9164.4 kg (20,204 lbs) per year, excluding milk consumed by her calves, whereas the same average value for a single cow in Israel was reported in the Philippine press to be 12,240 kg in 2009. High production cows are more difficult to breed at a two-year interval. Many farms take the view that 24 or even 36 month cycles are more appropriate for this type of cow.
