 Question: can you have a heart attack from laughing Context: The film's mainstream success had backed up the initial idea of making a trilogy. The sequels, The Matrix Reloaded and The Matrix Revolutions, were filmed simultaneously during one shoot (under the project codename ``The Burly Man''), and released in two parts in 2003. They tell the story of the impending attack on the human enclave of Zion by a vast machine army. Neo also learns more about the history of the Matrix and his role as The One. The sequels also incorporate more ambitious action scenes and visual effects.
 Question: was the matrix originally supposed to be a trilogy Context: In most earthquakes, the epicenter is the point where the greatest damage takes place, but the length of the subsurface fault rupture may indeed be a long one, and damage can be spread on the surface across the entire rupture zone. As an example, in the magnitude 7.9 2002 Denali earthquake in Alaska, the epicenter was at the western end of the rupture, but the greatest damage was about 330 km away at the eastern end. Focal depths of earthquakes occurring in continental crust mostly range from 2 to 20 km.Continental earthquakes below 20 km are rare whereas in subduction zones earthquakes can originate at depths deeper than 600 km.
 Question: is the greatest intensity of an earthquake always found at the epicenter Context: Vena amoris is a Latin name meaning, literally, ``vein of love''. Traditional belief established that this vein ran directly from the fourth finger of the left hand to the heart. This theory has been cited in western cultures as one of the reasons the engagement ring and/or wedding ring was placed on the fourth finger, or ``ring finger''. This traditional belief is factually inaccurate as all the fingers in the hand have a similar vein structure.
 Question: is there a vein that runs from the ring finger to the heart Context: All white blood cells have nuclei, which distinguishes them from the other blood cells, the anucleated red blood cells (RBCs) and platelets. Types of white blood cells can be classified in standard ways. Two pairs of broadest categories classify them either by structure (granulocytes or agranulocytes) or by cell lineage (myeloid cells or lymphoid cells). These broadest categories can be further divided into the five main types: neutrophils, eosinophils (acidophiles), basophils, lymphocytes, and monocytes. These types are distinguished by their physical and functional characteristics. Monocytes and neutrophils are phagocytic. Further subtypes can be classified; for example, among lymphocytes, there are B cells, T cells, and NK cells.
 Question: does a white blood cell have a nucleus Context: Celery salt is a seasoned salt used as a food seasoning, made from ground seeds, which may come from celery or its relative lovage. It may also be produced using dried celery or seed oleoresin.
