 Question: can you have a heart attack from laughing Context: With the AFL--NFL merger of 1970, the newly merged NFL was granted a Sherman Anti-Trust Act exemption, which emboldened some team owners to expand the exhibition schedule and to require season-ticket holders to pay for one, then two, then three home exhibition games if they wanted to keep their season tickets. The exhibition season then became, and remains, a large source of owner revenue that is not shared with the players. From 1970 through 1977, the NFL season consisted of 14 regular season games and six exhibition games, sometimes but not always three at home and three away (the 1973 Washington Redskins, for instance, played all but one of six preseason games at home), with some played at neutral sites. Since 1978, the regular season is 16 games, and the exhibition season was cut from six to four games. Two teams play five exhibition games, however.

However, even on a flat surface it is possible for a coin to land on its edge, with a chance of about 1 in 6000 for an American nickel. Angular momentum typically prevents most coins from landing on their edges unsupported if flipped. Such cases in which a coin does land on its edge are exceptionally rare and in most cases the coin is simply re-flipped.

In an interference engine the timing belt or chain is also critical to preventing the piston from striking the valves. A timing belt is usually a toothed belt -- a drive belt with teeth on the inside surface. A timing chain is a roller chain.
